Merge lp:~unity-team/unity/more-places into lp:unity

[Neil J. Patel]

- Fixes some spacing
- Cleans up group-render implementation by moving the logic to the Tile class
- Adds support for loading icons
- Adds support for loading application icons
- Adds support for launching desktop files

This is mostly some polish for this release. I need to clean this up and separate out some of the pieces for next weeks release, including the new expanding group view and a pixbuf cache

[Mikkel Kamstrup Erlandsen (kamstrup)]

Approved!

It seems to be a bit heavy on the IO since you create all those GDesktopAppInfo's (which parses the keyfile each time I believe) but it works fine. I think we should address that later with some caching magic.
