Merge lp:~david4dev/slingshot/fix-804518 into lp:~elementary-pantheon/slingshot/slingshot

[David Green]

Fixes bug 804518:
  - Slingshot now launches in the background. This makes it suitable for auto starting.
  - If the slingshot executable is run and an instance of slingshot is already running, the slingshot window will be activated. This shows the launcher without much delay.
  - Slingshot now monitors /usr/share/applications and ~/.local/share/applications so that it updates whenever launchers are added/removed (normally when installing/uninstalling apps).
  - Slingshot no longer shows/unshows the desktop. This is because I couldn't work out how to this with the new functionality. IMO this is actually better because you can still look at the windows you have open. This may be useful, for example, if one of them is a guide telling you which application to run.
  - Removed gradient to improve readability when running slingshot over windows (or light coloured wallpapers).

If slinshot is already running, it now shows the existing instance if it is hidden and hides the existing instance if it is showing.

fixed issue with slingshot showing behind windows

62. By David Green on 2011-08-10

Now shows/hides the desktop again

[xapantu (xapantu)]

Apparently, this branch has been merged separately (i.e. the branch hasn't been merged directly but parts were taken) so we have these features in the trunk now.
Thanks for your work :)
