Updated the Editor QT creator project file to latest changes.
Refreshed the AUTHORS file while seeing it.
Got rid of the defs.h file.

Now the class and struct declarations should belong in their respective files.

It made me earn 40 sec per full compilation process when using C::B 12.10
and its mingw-gcc and reduced the unstripped debug binary by something half a megabyte.

So I'm definitely going toward this removal.
