Cleanup and polish of the Citation dialog:

- now simple citation insertion can be done with the keyboard only (enter key will close the dialog and insert the chosen key).
- now search also within bib entry information (very fast)
- new case sensitive option
- new regex option.
- QCitation: code simplified, some code went to ControlCitation.
- QCitationDialog: code simplified
- lots of polish in the dialogs...
