- Update bottom-line/status bar with applicable control keys (Ctrl-C/X/V)
- Ctrl-X now cuts the text to the Clipboard, rather than just deletes
- Ctrl-C now copies the text to the Clipboard, rather than aborts
- Ctrl-V now pastes from the Clipboard into the text field, not toggles insert
The old CUA keyboard equivalents for Copy/Cut/Paste are supported too
(Ctrl-Ins, Shift-Del, Shift-Ins)
The system Clipboard is used, just like with the mouse methods of copy/paste.

ufic.showbuf() changes (used for displaying help text):
- Fixed the "End" key behavior (actually goes to the bottom of the text)
- Display up and down arrow glyphs in the lower-right corner/border to indicate
  if the text can be scrolled up or down (e.g. with the arrow keys/etc.).
  If the arrows are mouse-clicked, that simulates the arrow keys being hit.
