Merged changes from branch "sput" r56:61 back into trunk. This contains a lot of new stuff in all parts of quassel. It also contains a serious bug, which for some reason causes quassel to crash every few starts. Merging this only because of public request. So don't complain - I've warned you!
Merged changes from branch "sput" r50:55 back into trunk. This includes my work of the past few months, most notably a pretty complete rework of the buffer management and much other GUI code, as well as our new ChatWidget which is now functional enough to be used. Probably most of the GUI code now looks quite different. There have also been many cleanups, the obsolete network/ directory is being removed, and I have started to document some things.
