Start fuzzy searching for repositories after typing "<login>/"

[bswinnerton]

I'm not sure if this is possible, but it'd be great if the action could start fuzzy searching for repositories right after the user types something like bswinnerton/ (which would require an API call).

I think this should be possible using the Suggestions Script functionality. We'd just want to make sure that it doesn't start executing until after a / is typed in order to avoid a collision with #22.
