Add fixes/speed-up from kde's qt-copy:
- let moc handle optional identifiers
- speed-up qt startup by looking up some settings at qapplication startup
(use one single qsettings object)
- some cursor/refresh bug.
Most notable improvement seems to be font-handling, especially unicode stuff.
Configured to relocate plugins at a reasonable place. Includes *sql
plugins, though they are thoroughly untested at the moment.
Works good enough to recompile xglobe for instance. Still work to do
though, some paths are probably incorrect yet.
