CursurInvoker: add long-press gesture to raise Palette

Browse Source 
This adds long-press gesture detection to the CursorInvoker
used in the EventIcon. This will make this gesture available
for the View icons for example.

We need to keep a boolean around to detect when a lon-press
event has happened and ignore the button-release event in
that case.

We add as well checks in the CursorInvoker and WidgetInvoker
for the enter events if they are of type Gdk.CrossingMode.NORMAL,
otherwise the Gdk.CrossingMode.TOUCH_BEGIN enter events that are detected
when a touch starts are handled and interfere.
