Title field in editor may be recognized as username field in some browsers

[stianjensen]

We saw an issue today where someones username was saved as a new article title.

The issue turned out to be caused by the user's autocomplete, which overwrote the value of the title field with the user's username.
This was first discovered after hitting save, and then corrected.

We should investigate whether we can do something to ensure browsers don't overwrite the value of this field.
Maybe we can disable autocomplete for the field altogether.
