- fix delete user but repository watches are not decreased

If the host setting looks like a unix socket (leading by char '/'), will use unix(host) as connection string

README: fix typo

- templates/org: mirror fix on name output
- routers: add missing error check

- routers/user: little code format
- conf/locale: update French locale

Not sure why, but xorm ignores the num_issues and num_closed_issues
columns when updating, even though the values changed.

Listing them explicitly fixes the issue with the wrong issue counts

The normal go get protocol is to show the go-import meta tag when ?go-get=1 is appended to the url. This commit implements that behaviour and cleans the go-get option from the repository settings page.

cmd/web.go: check version after load config

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)
