* Use match instead match?

`DeviseMailer` did not correctly handle display names set via
`Gitlab.config.gitlab.email_display_name` if they contained spaces or
special characters. It has been adjusted to handle addresses in the same
way `BaseMailer` does.

We cannot support these features at this time and they are just
cluttering the UI.

removed to lower complexity of the project creation page.

2FA could be enabled but still was not usedi on sign-in.

The following formerly separate commits have been merged in:

* Adjust 'Sign in' button for GitLab's CSRF protection

  adjusted to send a POST request.

* Opt out of turbolinks for 'Sign in' button

The project variable can hold an object which is not an instance of
