All known Generics bugs fixed in GExperts code formatter

[dummzeuch 1506]

I have just finished fixing all known bugs in the GExperts code formatter that were related to Generics. On top of that I fixed a few others.

I am sure there are still more though, but because I rarely use Generics I haven’t seen them yet. So I need your help: If you have a lot of source code with Generics, please compile a new DLL and try the formatter on that code. Report any bugs on SourceForge.
