Update Features from 1.0-alpha5 -> 2.0-beta1

Took a fresh pull of the easy .make today. Noticed this...

Could not locate features version 7.x-1.0-alpha5, will try to        [warning]
download latest recommended or supported release.

7.x-2.0-beta1 is actually downloaded, but it would be better to have the correct version in the .make.

I've already updated this in the moderate and difficult kits.
