[Kst] kst_threading_branch: kdeextragear-2/kst/kst

[George Staikos]

CVS commit by staikos: 

enough to demo multithreaded updates with one thread doing the updates.  Not
sure if we can do better, but at least it's not in the GUI thread anymore.
It's really horribly thread-unsafe in general though, so doing more than
loading a file and looking at it is bound to cause crashes, deadlock, or other
weird problems.
