[PyKDE] PyQt and SIP configure.py Changes

[Phil Thompson]

With tonights snapshots I have completed the refactoring of the SIP & PyQt 
build system so that sipconfig.py no longer contains any configuation data 
specific to a Qt version. This means that SIP is now completely independent 
of Qt and it is no longer necessary to rebuild it when switching between 
building PyQt3 and PyQt4.

A consequence of this is that the function of some of SIP's configure.py 
command line flags have been transfered to PyQt's configure.py (though not 
always with the same name). You may need to change any scripts you have that 
automate building SIP and PyQt.
