only attach notifications when the tray exists

[GoogleCodeExporter]

When I login, it usually takes a very long time for the panel's
notification area to become active; in other occasions, it also takes a lot
of time for specto's tray icon to appear on the panel.

There are a few solutions to consider.
- listen for a signal that tells us the tray is ready and the icon has been
shown, if such a thing exists?
- try getting the position of the tray icon, and if it is nonsensical, use
"not-attached" balloons?
- ???

Something else to consider as part of this issue: we should not be trying to 
attach
balloons to the tray if the tray is not available for some reason.
