Speed Speed Speed...

main.cpp disabled messagehandler..
TableView: do not update View from setCategory if category was not changed
and if not first setCategory
Inline editing is working again
current is working too
Fixed sorting

MainWindow:
 Show Event
 and Edit event does work again
 Try to avoid calling sorted or allRecords unneeded...

 10.000 todos on SQL does feel fast

I need to get it down some more... maybe tweaking libsqlite a bit ( some compiler switches and disable asserts )
Before I implement new features I want to get down to 2-3 seconds loading
of Data
The UI will instantly pop up and then load the stuff within seconds
