"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)

* fix all the bugs in issues and pulls on dashboard

* small fix and refactor

* add method getRepoIDs for IssueList

This change corrects a few logging issues:

 * Standardized formatting errors with '%v'.
 * Standardized failure warning word usage.
 * Corrected an instance of using the standard log library when
   the gitea log library should be used instead.

- Add site-wide option DEFAULT_KEEP_EMAIL_PRIVATE.
- Add the new option to the install and admin/config pages.
- Add the new option to app.ini in the service section.
- Add the new option to the settings struct.
- Add English text strings to i18n.
- Add field KeepEmailPrivate to user struct.
- Add field KeepEmailPrivate to user form.
- Add option to UI.
- Add using noreply email address if user has "Keep Email Private".
An email address <LowerName>@<NO_REPLY_ADDRESS> is now used in commit
messages (and hopefully all other git log relevant places). The
change relies on the fact that git commands should use
user.NetGitSig().
- Add hiding of email address in UI, if user has set "Keep Email Private".
- Add condition to show email address only on explore/users and user
pages, if user has not set "Keep Email Private".
- Add noreply email in API if set "Keep Email Private".
- Add a new service setting NO_REPLY_ADDRESS. The value of this
setting is used as the domain part for the user's email address in
git log, iff he decides to keep his email address private.
If the user decides to keep his email address private and this
option is not set 'noreply.example.org' is used, which no MTA
should send email to.

Add NO_REPLY_ADDRESS to conf/app.ini.

* Check primary email address fields on CreateUser

As this check wasn't available, uid=1 (and possibly guests too, if registration is open) is able to register new users with existing email addresses. This leads to numerous 500 errors.

* Lower the email first. Then check

* restrict creating organizations based on right on user

* revert bindata.go

* reverse vendor lib

* revert goimports change

* set AllowCreateOrganization default value to true
