clean up

[TillSchlemmermeier]

lets put all the G's and E's in folders to clean up the filestructure and get rid of deprecated files

[Co-eus]

• [ ] check cube_utils for old routines
• [ ] delete gui_1.2.py
• [ ] put gui stuff in a seperate routine/file, so that the main file is cleaner
• [ ] automatic addition of generators/effects using os.listdir or os.path
