A job configured to use a git repository provided by gitlab will fail to save if the repository browser is configured to be gitlab and either no value is entered into the gitlab version field, or a value is entered which can't be converted to a java double.

Since the current version of GitLab on the cloud is 7.11.4.ee, that means I needed to list the version as 7.11. If I listed it as empty or as 7.11.4 or as 7.11.4.ee, an exception is thrown when trying to save the page.

The gitlab browser constructor needs to be more forgiving of user input
