new repository actions

[clkao]

• add common tags
• add to dev team
• check for license file (or readme content) - if not provided, create an issue

github doesn't seem to provide new-repo hook for organizations, so we probably need to scan for new repos and apply these actions.

optionally allow a flag in g0v.json file to opt out issue label creation?

to get all repositories listed on g0vhub:

curl https://g0vhub.firebaseio.com/projects.json | jq  '[.[] | .["repository"]["url"] ]'
