Subject: [PATCH] * Watch the system clipboard for changes. * On the event of a
 clipboard change, check if the clipboard contains text   now and replace the
 contents of the internal "mouse clipboard". So when   right/middle clicking
 into the Terminal, the current system clipboard contents   are inserted. As
 soon as the user selects text in the Terminal again, that   text will have
 priority over the system clipboard, as before.

Fixes ticket #3700.
