SciDAVis - Improvements SVN-temp

build files. Some bits deliberately not ported:
CONFIG+=thread win32:DEFINES+=Qt_THREAD_SUPPORT: We don't use threads.
DEFINES+=QT_PLUGIN: Added automatically if CONFIG contains plugins.
win32:DEFINES+=QT_DLL: We're not building DLLs.
QT+=qt3support: Try to port everything to pure Qt4. If necessary, this flag
can be temporarily added again for individual modules.
- Removed resource.h, which was only used by iPlot.rc, which has been removed.
- Some consistency improvements in Project.
- Started to re-integrate scripting support.
