HUGE COMMIT :) - clean qml plasmoid, fixes #23

-- this is a fantastic release the plasmoid is clean qml from now on,
there were some difficulties in supporting all the feautures
but only the workflow.cpp functionality is missing which is going
to be implemented the next days...
IMPORTANT: all the functionality moved to the clean qml plasmoid

--Everything is in its place :) all the functionality from the
previous hybrid c++/qml plasmoid moved to clean qml. Even the
current activity icon support for the panel. Actually this one
is a qml element now so animations and a lot of magic can happen
in the panel... :)
