I was confused by current wording, which seemed to imply that
*records* would be initialized, while instead the function initializes
the *git repositories* instead, where missing but referenced.

Amended with string to bool change in API SDK.

Fix for #1013: adds "bindata" to tags by default, as without this the
resulting docker image won't start, as it doesn't contain locale files.
Verified to work even if you specify TAGS="bindata" such that it appears
twice.

use terms instead of fields as variable name to avoid confusion: NewPhraseQuery(terms []string, field string)

* initial stuff for oauth2 login, fails on:
* login button on the signIn page to start the OAuth2 flow and a callback for each provider
Only GitHub is implemented for now
* show login button only when the OAuth2 consumer is configured (and activated)
* create macaron group for oauth2 urls
* prevent net/http in modules (other then oauth2)

* sign up with button on signin page (als change OAuth2Provider structure so we can store basic stuff about providers)

* from gorilla/sessions docs:
"Important Note: If you aren't using gorilla/mux, you need to wrap your handlers with context.ClearHandler as or else you will leak memory!"
(we're using gorilla/sessions for storing oauth2 sessions)

* use updated goth lib that now supports getting the OAuth2 user if the AccessToken is still valid instead of re-authenticating (prevent flooding the OAuth2 provider)
