Currently, gnome-terminal uses a VTE match to look for URLs and other clickable links, which you can then open either by <Ctrl>+clicking them or by right-click + Open Link. But both require to use the mouse.

This patch, tested on both master and v3.8.4, offers an alternative. It provides a new feature to search for URLs that are in the currently visible region of the VTE buffer, and pops up a menu with one entry per URL that, when activated, opens the corresponding link in the browser. This feature is mapped to the <Ctrl>+<Shift>+U keybinding. This allows for opening any link that the user "sees" in the terminal without having his/her hands leave the keyboard.

The popup menu is positioned at the center of the terminal window to avoid loosing the focus after activating a menu item (in sloppy-focus window managers), and each entry in the menu is nicely formatted like so:

  <b>Domain.tld</b>
  <span size="small">http://the-full.url.com/path</span>

Hopefully I've covered all the bases for references cleanup, etc, but I'd appreciate a double check, especially with regard to 'match', which I add as a data property to each menu item and I'm not sure if those get freed by gtk_widget_destroy() or not.
