Add "Paste" command to krdc (#102).

This adds a "Paste" command to the toolbar which sends the current
clipboard content to the remote host as key presses.

Not implemented for RDP as we appear to defer to rdesktop and I'm not
sure if we can reliably do it there (also krdc RDP isn't working for me
right now).
