GaiaTheCreator v.0.0.1.2

I finally found the error that made the editor nonexecutable! The reason was a wrong file path reference to the xml file that holds all the data values.
For this temporary solution the xml file has to be copied into the project directory to make it work.
I included a readme file that contains the editor's version history and some important notes.

The new features:
- Pause screen texts are fully editable
- Map data sets can be edited (only music edit is confirmed working)
- Compressed tilesets consisting of more than one single tileset are
  now treated as one tileset internally
