- routers/admin: add rewrite update hook operation
- conf/locale: update locale file due to ini behavior changes
- cmd/cert_stub.go: remove useless code
- cmd/fix.go: no longer need fix command(at least now)

This commit does a lot of the work of refactoring the access table in a table with id's instead of strings.

The result does compile, but has not been tested. It may eat your kittens.

The previous behavior was to set default values only if user.name was
not set, but to always set it for both. This only sets a value if there
wasn't one; this fixes cases where someone has a user.name but no
user.email (see included Dockerfile) or someone has a user.email but no
user.name (before the email would have been over-written).

Git user.name and user.email will now be set to the standard values

  - Gogs
  - gogitservice@gmail.com

if user.name is not set or empty.

If user.name is set and user.email not, it will leave it this way.
