Plasmoid presence setting and displaying

[Alin Marin Elena]

hi,
there maybe we should keep the plasmoid simple... and limited to setting 
presences...
by default it should display only the global presence and status... I like the 
flipping buttons that nwoki used...
it should add a more button that will give the chance to set per account 
presences... for the ones in need of such a thing... (something like the 
networkmanager plasmoid...)
