This reverts commit c226e92284c7b4b405352814155dd5da3458e029, reversing
changes made to 80b23854bc.

- update some locale files

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

The "PHP" formatting function doesn't add anything, except an undocumented date format.

All usages in the templates have been replaced with DateFmtShort and DateFmtLong for convenience.

- 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)

- templates/user/settings: fix email panel nav highlight

Also, change all current 'emails' to 'e-mails'.
Still todo: some CSS for the user/settings/email page, but that is not my specialty

All basics are implemented. Missing are the right (localized) strings
and the page markup could have a look at by a frontend guy.

Addresses issue #399

Removed trailing whitespaces with

```sh
for file in `grep -r " $" * | cut -d : -f 1 | sort | uniq | grep -v " "`; do sed -i 's/[ \t]*$//' $file; done
```

and some handwork.
