Now a super user has the possibility to create an "open-bar" runner. A
flag is entered in the database to specify its type. When specify like
this, any application can be run on it.

The model has been updated to add the `open_bar` boolean field. The `account`
foreign key has been renamed to `user` to be coherent with the other models.
I updated the `RunnerForm`.

The template received a big update to separate the applications to select from
the open bar boolean. The open-bar element is seen only if the user is a super user.
