fix autogetn.sh for terminology for gettext

so i've been having trouble building for the past while unless i git
clean our build files etc. - it turned out to be the autogen.sh, so
i'm using one that works from elm. :)
fix focus issue due to "mouse_over_focus" conflict. Closes T1380
don't waste cpu mouseover when the mouse is not moving. Closes T1457

_termio_link_find() is the real culprit here but it's not yet its time to
get rewritten.
