When calling cleanUpComponent KGlobalAccel checks if there are no
shortcuts active, otherwise it will refuse to clean the component.
For a desktop file component (aka KServiceActionComponent) all
shortcuts are deactivated inside cleanUpComponent. For a regular
Component we have to do this manually.
If a QAction is destroyed, KGlobalAccel will automaticaly set it
to inactive. To prevent this put them on the heap and intentionally
leak them as it did before.
CCBUG:437364
Because we have changed the name of the desktop file, this also
changes the name of the kglobalaccel component. I have adjusted the program so
it checks which of the two old components is active and then sets the shortcuts
on the new one. I have opted for this because we cannot guarantee the order of
update scripts.
* Don't autostart KRunner, use actions in the desktop file to
define global shortcuts and actions
* install its desktop file in share/kglobalaccel to make shortcuts default
* expand commandline options to permit more control via commandline
