Make ComboBox editable

In addition
- Added text completion
- Added validator
- Added accepted signal
- Added activated signal
- Added textAt function
- Added find function
- Added keyboard indexing for non-editable as well

Note that we do not support adding values to the model,
but leave this up to the user to handle in onAccepted.
