Merge branch 'user-bio-improve' into 'master'

Improve the formatting for the user page bio

Resolves #13406.

Problems, per the Issue above:
- The bio has an extra period appended by the HAML view.
- The bio isn't given its own line, not differentiated from username and account creation date.
- The bio is allowed to span almost the full width of the container, would probably look better if it were only allowed a max width of something like 750px.

This commit:
- Separates the User page bio from the username and account creation
date.
- Separates the pseudo-selector adding a Middle Dot out from the
`profile-link-holder` class and into a `middle-dot-divider` class.
