[PyKDE] New Signal/Slot Implementation

[Phil Thompson]

Tonight's SIP and PyQt snapshots will have revised support for signals and 
slots. This is just a warning that it's a fairly fundamental change and there 
might be outstanding issues.

The reason for the change is to support queued and inter-thread connections in 
PyQt4 - which seem to work now.

This involves a change to the internal API so everything need rebuilding.
