Experimental files lens

[Michal Hruby]

Hi everyone,

some of you might have noticed that there's a special version of 
unity-lens-files in the ubuntu desktop PPA (ppa:ubuntu-desktop/ppa), 
which augments the search results provided by Zeitgeist with results 
obtained by invoking locate.

Please check it out and let us know what you think about it (testing on 
low-end hardware particularly welcome).

Thanks,
Michal
