Anton Khirnov 87366694d8 Remove the internal GUI 
The GUI is badly designed and too closely coupled to the internal
details of other code. The GUI code is in bad shape and unmaintained
for years. There is no indication that anyone would maintain it in the
future either. Even if someone did volunteer to implement a better
integrated GUI having the current code in the tree probably wouldn't
help much. So get rid of it.
