Debugger: Make tooltips use standard text editor tooltips.

Browse Source 
Extend text editor tooltips by a 'widget content', making
it possible to show any widget utilizing the fact that the
QTipLabel actually is a frame (and thus a container).
Introduce concept of 'interactive' tooltips and modify
the tooltip-closing mechanism such that simple interaction
is possible. Emit the base text editor's tooltip signals
with the correct position and add API to calculate the tooltip
position from the cursor position.
Add API for pinning tooltips to the text editor (by removing
them from the QTipLabel layout).
Modify the Debugger's tooltipmanager not to manage tooltips
under TextEditor control and to take over control only once
tooltips are pinned.
