FEATURE: Kexi now supports manipulating image data in the table view,
and clipboard actions.

Forms

- cut/copy/paste shared actions work for form widgets in data view

Table View
- context menu from image box reused in the Table View's cell editor
- cut/copy/paste/clear actions work for the image cells, including shortcuts
- cut/copy/paste/clear actions work for text/number/boolean cells
- fractional character ("," or ".") can be entered as the first character for
floating-point data types, what means 0.xxxxx
- fixed updating row number info in the record navigator and updating the current cell after column sorting
