The previous filter's negative sides were that: 1) it switched the user from the favourites view to the list view for presenting the results (not obvious for a novice user how to escape that view); 2) that the list view hides all non-matching activities completely from the view (easy to end up with a blank set of filter results if you accidently press a couple of random keys). Gonzalo's feature implementation avoids both those issues, and even allows the ghosted items still to be interacted with, so I'm happy so see it land.

I tested with 40 icons in the favourite spiral with some non-sugar compliant activity icons installed.

An accidental filter search could make icons look like they had no resume state (e.g. an accidental press of the space bar).

Thanks Gary for this in depth analysis and Gonzalo for the new patches. 
I pushed them now.

One point of criticism: I think the alpha value is way too high. The 
difference between a filtered and an unfiltered value is not enough (the 
0.33 value works well for the launcher though). I had better experience 
with a value of 0.15 for example.

Let's let people try it out and revision on Monday.
