Expand character set of usernames created by Omniauth

When a user is created by Omniauth, Gitlab tries to assign the username based on the information provided in the auth hash. If no nickname is present, it uses the part of the email address before the @. This portion of the email address is run through the `parameterize` method, presumably to convert Unicode characters to ASCII.

`parameterize` strips out a number of characters that are valid in usernames. For example, `john.doe` is a valid Gitlab username, but parameterize will turn this into `john-doe`.

Instead of `parameterize`, this merge request uses `normalize` to convert non-ascii characters. This allows all acceptable characters to be used when creating a username from an email address. 

See merge request !660

Remove check icon from merged MRs

Now that GitLab CI exposes the status of each MR in the MR page it seems "redundant" to have an extra icon next to the CI statuses.

The "downside" is with people that don't use CI and don't see the statuses, but I don't think that this is that big a change that would miss to anyone.
