Had some fun with the Level Editor. Removed the dependency on MiGLayo…
…ut by creating my own Panel instead. Tried to change as little as possible of the existing code, there should be no functionality changes except for one small thing: The warning text in the population tab did not update when you removed an entry, now it does. Also added what to write in the command line to compile and run the Level Editor, and added some more files to the ignore file
