Subject: [PATCH] Bug 17179 - Add keyboard shortcuts to repeat (duplicate) a
 field, and cut text

This patchset introduces an internal clipboard to the advanced editor
and provides some new functionality to make use of this:

Ctrl-X:       Now cuts a line into the clipboard area
Ctrl-Shift-X: Now cuts current subfield into clipboard area
Ctrl-C:       Copies a line into the clipboard area
Ctrl-Shift-C: Copies current subfield into clipboard area
Ctrl-P:       Pastes the selected item from the clipboard at cursor
Ctrl-I:       Copies the current line and inserts onto a new line below
Ctrl-Z:       Functions as undo - this was supported but now in the
dropdown help

To test:
Verify all functionality above and confirm it behaves as expected

Note:
Ctrl-v pastes from the system clipboard - codemirror does not have
access and this is why we use our "Clipboard"
For browser cut/paste please use mouse right click or context menus
Ctrl-P can be accessed as print by focusing outside the editor window
