Update version to 6.3.0; add configurable truthy condition values, improve condition handling, and refactor config messages

- **Configurations**:
- Introduced `truthyConditionValues` for customizable condition evaluation (`true`, `yes`, etc.) within conditions.
- Updated `config.yml` and `custom_gui.yml_example` to reflect new `truthy-values` option with expanded documentation.
- Added `%prefix%` support across configurable messages for easier customization.
- Refactored config messages to include a global prefix for improved consistency and user experience.

- **Parsing/Validation**:
- Enhanced slot validation in `Config`, issuing warnings for missing or invalid slots in custom items.
- Improved condition logic in `GUIUtils` to match against `truthyConditionValues` for greater flexibility.
- Added better error handling with warnings for unrecognized operators in conditional expressions.

- **Listeners**:
- Updated `InventoryListener` to handle additional edge cases in inventory interactions (e.g., shift-click within custom GUIs).

- **Other Changes**:
- Minor refactoring, improved readability with updated method calls and local variable usage.
- Updated dependencies and plugin compatibility for plugin behavior consistency.

Added support for PremiumVanish/SuperVanish.

Config option "essentialsx-hook" has been moved to:


Be sure to update your config.yml accordingly.

Enhance condition operators: expanded support for text and digit comparisons

Condition Operators:
Text operators:
=, ==, eq, equal_to, equals — equals
!=, neq, ne, not_equal — not equals
~=, ~~, contains, contains_string — contains
!~=, !~~, !contains, not_contains, not_contains_string — does not contain
starts, starts_with — starts with
ends, ends_with — ends with
matches, regex — matches regex
!matches, !regex, not_matches, not_regex — does not match regex

Digit operators:
>, gt, greater_than — greater than
<, lt, less_than — less than
>=, gte, greater_than_or_equal — greater than or equal
<=, lte, less_than_or_equal — less than or equal
=, ==, eq, equal_to, equals — equals
!=, neq, ne, not_equal — not equals
(All text operators above also work for digits, comparing as strings.)

---

- **`config.yml` & `custom_gui.yml_example`**:
- Documented and expanded available condition operators for text and numbers, including new options for equality, inequality, contains, regex matching, starts/ends with, and more.

- **`GUIUtils`**:
- Updated condition handling logic to support new operators with `PlaceholderAPI` replacements for placeholders.
- Added more robust string and digit comparison capabilities with detailed operator checks.
- Improved maintainability by using `switch-case` for operator evaluations.

This change significantly expands flexibility in defining conditions across the configuration and custom GUI systems.

Bump build version to 1.20.1

Hello everyone.

It's been a while since I've updated the plugin so I added a few new cool additions to the config.

First things first - you can now place custom items anywhere in the GUI itself. The heads will appear in the first empty slot.
The bottom row is reserved for custom items and the heads will not appear there.
The 4th and 6th slots of each row (depending on the GUI size) are always reserved for previous and next page buttons.



Example config for custom items:

Code (YAML):

custom-items:
  '1':
    material : WHITE_STAINED_GLASS_PANE
    slots:
      start : 0
      end : 8
    name : '&r'
    lore : [ ]
    commands:
      left-click :
       - ' [CLOSE ]'
      right-click :
       - ' [CLOSE ]'
      middle-click :
       - ' [CLOSE ]'
  '2':
    material : WHITE_STAINED_GLASS_PANE
    slots :
     - 9
      - 17
      - 18
      - 19
      - 20
      - 22
      - 24
      - 25
      - 26
    name : '&r'
    lore : [ ]

You can use:



Added additional actions for commands:

This will play a sound to the player.
The first argument is the sound, the second is the volume and the third is the pitch.
You can find a list of sounds here: https://www.digminecraft.com/lists/sound_list_pc.php
- '[SOUND] ENTITY.PLAYER.LEVELUP, 1.0, 1.0'

This will show a title to the player.
The first argument is the title, the second is the subtitle.
The last three are: fade-in, stay and fade-out times.
- '[TITLE] This is a title, This is a subtitle, 20, 60, 20'
Alternatively you can use opt out the subtitle or the times, or just the subtitle.
- '[TITLE] This is a title'
- '[TITLE] This is a title, 20, 60, 20'

You can send raw messages to the player:
- '[MESSAGE] this will send a message to the player'
- '[TEXT] this will also send a message to the player'

Added HEX color support.
Example usage: "#FF5BC8%player_name%"

Added ability to check text in conditions if a placeholder returns not a number.

Ex.:
The player will be included if "%example_placeholder%" returns value "hello".

Added an option to close the GUI if added [CLOSE] in the command section.
Removed CloseOnRightClick & CloseOnLeftClick in the Custom Items section.

Added a config option to require a specific permission for the user to be displayed.

Condition in the main config does not have to be enabled, where as in the Conditional GUI config the condition is used by default - in this case you can use a placeholder that would accept all players.

Downgraded the API version so lower versions can use the plugin.

You can now reload the plugin config from the console.
# Fixed some reload issues.
# Added some fail-safes in the config load in case of typos.
# Improved load/reload code.

(Provided example with PAPI Server expansion)

Usage example:
Added PlaceholderAPI support for custom item names/lores.
Added PlaceholderAPI support for left/right click commands.
The config now automatically updates with new config options.

Added ability in config to send clicked command as console.
Old config should work as usual.
