General:
* Cleaned up structure and removed obfuscation for GitHub publishment

• You may need to change/update the import of some classes when updating to this version
• The branches will be pushed at a later point (when the migration has advanced further)

* Optimized internal version checks to reduce amount of calls
* Check for unsupported versions

• If there is a fully unsupported version the plugin will now shutdown to prevent errors
  • Currently 1.17 & 1.18

* This version now fully support 1.15, 1.15.2 & 1.16 - 1.16.5

• This version includes the official release of TTA 5.0 so there will be no dedicated 5.0 release

Engine:
* Moved the getEngine method from the `TTA_Methods` to `TTA_BukkitVersion` class

BukkitVersion
+ New class called TTA_BukkitVersion which features several new API calls for easier version checking and management
