send mouse signals from View to containment

Browse Source 
--this is side-way path for mouse events and
more specific the mouse pressed, released
events to be sent from parent window to its
qml containment part. This way it is possible
to keep the original plasma applet behavior
such as original plasma tooltips and provide
Latte specific functionality such as animated
clicks from indicators.

NOTE: An investigation - testing took place in
order to check if this approach could be also used
for mouseMove events to be used for applets parabolic
effect. The result was that this was not possible because
there were too many signals and too much calculations
too identify for which applet the signal belonged to.
The parabolic effect was not fluid in that case and
could not catch up.
