v1.7.8 - 1.14.2 Support & Small Changes

Changes

• Added compatability for Minecraft version 1.14.2 (tested only for 1.14.2, 1.14.3 should also be okay).
• Merged a pull request from GitHub (thanks AlexTMjugador!):
  • Code refactoring
  • More customisable messages/strings (specifically, the GUI)
  • Rainbow chat colour now selectable in the GUI
• Small code formatting changes.

Tested on Minecraft versions 1.8.9 and 1.14.2 (everything between should work fine).
That's all for now.
