#30 GeoTray icon-hiding when I'm trying to use it

[Joel 'Jaykul' Bennett]

GeoTray's icon hiding works great, but if I click the
"expand" icon, it always re-hides after a
pre-determined amount of time. Obviously it has to
hide on a timer, but it seems to me that it should not
_ever_ hide while I still have my mouse over it,
because it's really annoying to be about to click on
something and have it vanish.

Can we use the same algorithm that is in the bar
auto-hide code for detecting when the mouse is over the
plugin, and then only hide after the time-out *and* the
mouse is not on us. (My recommendation would be to
simply reset the timer if the mouse is still in the
rectangle ... perhaps you'd want to default the timer a
_little_ shorter, but it seems like a plan)
