return success when the window is closed
clickable_url should be false whenever browser isn't set
disable clickable_url when no browser configured
if no browser, disable url hints
better warning for no browser
check if browser is null, not if clickable_url is false

Hints don't make sense if there's no browser set, but checking if
browser is null makes for cleaner code. Note this wasn't wrong,
clickable_url will be set to false if browser is null.

Copy URI to XA_CLIPBOARD on right click

Small patch that copies the match into the default clipboard using
gtk_clipboard_set_text(). Maybe consider which clipboard to use
(such as PRIMARY OR SECONDARY) instead based on a config option, although
that may be overkill (especially since PRIMARY is supposed to be ephemeral
or something)
