Merge lp:~sneakypete81/simplegc/simplegc into lp:simplegc

[sneakypete]

Add the ability to specify the fade in/out rate on a per-widget basis.

[Sam Bull (dreamsorcerer)]

This will be refactored in the next major release, to provide more flexible animations. I'll make sure to allow custom speed changes in the default animation. If you want to be updated on progress, I've added a bug you can subscribe to: https://bugs.launchpad.net/simplegc/+bug/1169738
