Update com.trolltech -> org.qtproject in the bootstrapped tools

The tools will now generate the new org.qtproject annotations only,
matching the XML generator in the library. They accept both types of
annotations as input though -- and will generate a warning about the
older one.

This commit should be backported to Qt 4, so XML files can start to be
ported.
