#313 Clear selection On Paste

[MichalW]

This option is analogous to clear selection on copy from settings -> behaviour menu. It would make Console2 more compatible with linux enviroments like rxvt, kosnole or gnome-terminal. It is very easy to implement because fucntionality is already there in source code. I could try to make some patch and send it to you if you agreed to integrade this functionality, of course after you review and accept the patch.
