Code review comment for lp:~jbicha/unity-asset-pool/drop-obsolete-icons

I'm putting unity, webapps-applications, ubuntu-settings in there too. The first two (especially the second one) are for tidying up and the third holds the new launcher for Shell. I had uploaded that before but I messed up the paths for the icon theme so it wouldn't have worked once u-a-p dropped the icons.
