Red-discordbot: !cog info <repo_name>

[irdumbs]

listing description of repo.

perhaps we could ask for an optional info.json in the repo instead of just pulling the description

[tekulvw]

Should also probably add !cog uninstall <repo> <name> while we're at it

[irdumbs]

Also could we provide a link back to their repo from the repo info? :)

Seems like a good idea to me

Done and added.
