I'm removing the 'beta' branding from the Android version of the Commons app for our next release.

This provisional commit replaces the current beta icons with the icons I found in the WMF design DropBox, and also tosses in a copy of the PSD source file (compressed as it's huge) under a 'scratch' directory so we don't lose it:

Design folks who worked on the icons, please confirm if this is the correct icon set -- it's a little different from the beta icon, and I don't know whether that's deliberate or not. :) If there are newer assets for this please let me know and I'll merge them instead!

Thanks!
