CVS commit by faure: 

Reload plugins after enabling/disabling them so that no restart is necessary.

Show plugins for the active part, instead of always khtml, so that one can also
configure the konqiconview/konqlistview plugins with this dialog.

Added .desktop files for those plugins so that they appear there.
