Request: Support for emulating CUA mode?

[drgibbon]

CUA mode enables the more well-known keys for cut/copy/paste/undo. From the Emacs manual;

When CUA mode is enabled, the keys C-x, C-c, C-v, and C-z invoke commands that cut (kill), copy, paste (yank), and undo respectively. The C-x and C-c keys perform cut and copy only if the region is active. Otherwise, they still act as prefix keys, so that standard Emacs commands like C-x C-c still work.

This would be handy I think, since it can get confusing copying/pasting between a browser with keysnail support and one without (e.g. from Firefox to Chromium).
