Remove remark that Adblock Edge uses less memory than Adblock Plus

It's not true. Ablock Edge is an (apparently unmaintained) fork for an older version of Adblock Plus. Apart from the rebranding, the only change is the removal of the acceptable ads option.

Disclaimer: I work on Adblock Plus. It's totally fine by me if you don't like the idea of acceptable ads and don't want to recommend ABP for that reason. But I'd like to point out that acceptable ads has nothing to do with privacy, EasyList doesn't block most tracking to begin with. You already recommend Disconnect, which takes care of that.
