Implemented the "warp-cleaner" and "warp-clean-time" options to the "config.yml" which remove warps based on inactivity.
Moved most of the GUIs back to an async thread to remove some delays and spikes caused by sorting features.
Warp Icons no longer require a skull to be built off a player. If the operation is unsuccessful, it will be skipped and the material ARROW will be used.
The SQLite backup system now replaces itself upon startup as long as the "warps.db" exists instead of only when the backup file doesn't exist.
Warp sorting now properly strips the warp names of color codes to properly compare each alphabetically.
Removed extra teleportation calls from the user "/back" command to ensure the last location is updated correctly.
The "teleport-last-location" message in the "lang.yml" has been adjusted to contain the {duration} placeholder and have the placeholder replaced based on the operation.
Fixed a couple of default color codes for some messages in the "lang.yml".
Fixed an issue where command created and existing warps would not contain the default color codes causing italic warp names.
Fixed some placeholder issues involving standalone teleportation commands.
