QmlInspector: Unified mouse and keyboard event handling

Introduced a common AbstractTool interface so that the
AbstractViewInspector can forward mouse and keyboard events and
also implement the keys to switch tools.

The AbstractLiveEditTool still exists as the base class for all
QDeclarativeView based tools.
