The old migration had a few issues:
 - It left old column names around
 - It did not give the right access levels for owners and admins

Also, this includes a migration that fixes the authorization of owner teams, which was previously ORG_ADMIN (instead of ORG_OWNER)

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.

- 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)

- models/issue.go: format comment type names

- modules/base/markdown.go: fix issue link issue
- routers/repo/view.go: remove useless code

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

Code-wise: the fixing-part of the code now doesn't reference the issue any more, because this is done by the referencing-part of the code, which is called just before.

Fixes #462, #668, #732.

- routers: use new binding convention to simplify code
- templates: able to set HTTP port number in install page

It is now possible to input ssh keys in a number of formats: openssh, SSH2 or just the base64 encoded key.

refs #763

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).
