This reverts commit 78ba7bcf.

This reverts commit 07ec2c7b.

`DeviseMailer` did not correctly handle display names set via
`Gitlab.config.gitlab.email_display_name` if they contained spaces or

cluttering the UI.

removed to lower complexity of the project creation page.

The following formerly separate commits have been merged in:

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

  571ba5a7. The 'Sign in' button has been
  adjusted to send a POST request.

* Opt out of turbolinks for 'Sign in' button
