Adds real support for ToolTips.

Browse source 
This patch changes the Event drawing so it can display tooltips. It is now
the responsibility of the item to show / hide a tooltip.

A bit of code-refactoring got on here too because I was using only
QGraphicsItem calls and I wanted to use a hover in / hover out event
to show / hide the tooltip.
