Rename Repo to "ng-intercom" to match the npm package

@wbhob, I would like your feedback on this.

I agree. We’ll need to coordinate this change with the next npm release so the links are accurate

[scott-wyatt]

Cool, good news is, as long we don't reuse the angular2-intercom namespace in this organization, github will just redirect requests to the new name.

Sounds good. ready when you are

[scott-wyatt]

Renamed! Cheers
