v1.13.4 - Default-to-GUI Setting & Minor Fixes

Changes:

• Added a new setting, command-opens-gui. When set to true, running /chatcolor will open the GUI instead of telling you your colour.
• Fixed some messages that were either missing a prefix, colour, or both!
• Refactored some code internally that was quite gross.
• Default confirm-timeout value changed to 15 seconds.

• Fixed a bug where legacy colour codes (a, b, c, etc.) couldn't be used in gradient colours.
• Fixed a bug where /chatcolor reset would not reset the GUI or custom colours. Please make sure to backup your configs if you use this!

That's all for now, but stay tuned for the long-awaited SQL support update coming very soon!
