Inconsistent use of "Sources" in Filter Results in Unity lenses

[Jeremy Bícha]

With current Saucy, only the Home lens and the Applications lens has a Sources filter in Filter Results.

For consistency, I recommend that either all lenses use the Sources filter or none do. (If you choose to remove the Sources filter, we could just direct people to the Search Plugins filter in the Applications lens for them to disable scopes that they don't want.)

Perhaps the Sources filter could be automatically generated from scopes that opt-in to a particular lens. In that case, bug1189026 and bug 1189040 are probably pre-requisites.
