Fix Copy/Cut/Paste issue in Vertical Edge text field (preferences) 

This commit allows Ctrl-V, Ctrl-C, Ctrl-X, Ctrl-A & Ctrl-Z in text field, so user can do paste, copy, cut, select all & redo/undo action respectively in Vertical Edge text field of Préférences dialog.

Also the paste content is controlled to allow only the number and white space.

Fix #13874, close #14586
