* Pastebin confirmation added; we were getting a lot of people accidentally

pastebinning sensitive information so I think this is a good idea.

* GTK now has pastebin, both for full log as well as the current selection

* GTK now has a menu

* GTK now has a statusbar

bpython.gtk_

- add pastebin url to clipboard (or show a popup) instead of status bar

- make statusbar only show aborted paste for a few seconds

bpython.urwid

- make keys work
