Add automatic termination

[GoogleCodeExporter]

First of all, if you have any Haxies, InputManagers, SIMBL plugins or
similar operating system hacks installed, please remove them first, restart
the program, and make sure the bug is reproducible without them.

What steps will reproduce the problem?
1.open an image and close.
2.the icon remains on the dock.


What is the expected output? What do you see instead?
I suggest that the icon may quit the dock after the last window closed, just 
like preview.

What version of the product are you using? On what operating system?
xee 3.05(22) on Mac OS X 10.8.4

Please provide any additional information below.

Yes, this is planned, but I'll need to look into how Preview does it, it uses 
some new API for this which I am not yet familiar with.
