update to 0.5.10
This release fixes a security bug (possible local exploit).
other changes:
* DBus support is now enabled by default
- improved screensaver support
* Added 'CHANNELPREV' event (for vdr-xine 0.7.10).
* Deferred preferences window initialisation until it's actually
  opened. (This noticeably speeds up startup.)
* Fixed some indexing errors in the playlist drag&drop code.
* Some small filename buffer usage cleanups.
