first, we can't make such a change until trunk opens for 4.3 development as it 
contains new strings.

the patch, however, is also incorrect in a few ways: not all panel 
containments are called "panel", and keeping a count is unecessary.

instead, simply loop through Corona::containments() and look for 
containmentType() == PanelContainment or CustomPanelContainment

moreover, i don't think this belongs in libplasma since not all plasma based 
applications will care about this. it really belongs in the desktop shell 
application.
