added experimental link to in-browser IRC gateway http://scrollback.io/p...

hey guys, scrollback.io is an IRC gateway plugin which is getting good adoption in the opensource community. I'd like to try sticking it on the Community page as an experiment. If the experiment fails, we can take it out; if the experiment works, maybe we can put it on a few more pages as appropriate.

(Full Disclosure: I know the founders personally and have invested a little bit of cash in their startup.)

my love to vahnee, robrt, etc.
