Level and room manegement options

[knot126]

Creators should probably be able to organise segments into rooms and rooms into levels from SHBT so that the user never has to touch the APK files. We could probably let the user enter the name of the segment and extend the findTemplatesPath() function to find open APKs and use that to save segments to. I'm not as sure what to do about room editing, since that is mostly scripting, but maybe we could have different text feilds for levels/rooms and use the quick test options for that?

We are sort of hitting the limits of the Blender UI with this.

Partial work has been completed for this in 2.1.5 via the "Save to APK" option, but there are no options to manege rooms, levels, game setup.
