Streamlining

Today was the day from hell in terms of work and school, but I still managed to get some streamlining done. The affected areas are mostly on the ui side, added syntax highlighting for #defines in the text editor, added a generator load graph and made single line text input a lot more user friendly. Also fixed a possible endless loop in the generator system. Hopefully tomorrow I can get the SAVE and LOAD operators up and running after which comes export and import for the texgen, and after that I can move on to 3D.
