Me: Sidebar: Decode entities for User's display name on /me profile sidebar

[oskosk]

Display names that used a special char, for example, an ampersand were shown like & on the h2 that shows the display name under the gravatar.

It used to look like this

Now it shows just the ampersand.

Tested, looking at code

LGTM.

The only feedback I have is that we should probably squash the commits here since the second commit is a fix for a whitespace issue that was introduced in the first commit.

[oskosk]

Done. Squashed.

Going to go ahead and merge as this solves the issue with escaping entities in the sidebar.

@oskosk and I discussed different options for also escaping values that are displayed in the inputs throughout /me.

I suggested that we could potentially decode the HTML entities in the valueLink method within form-base. The only issue I see with this is that we should preferably escape as we are passing the value in to the FormInput, FormTextarea, etc.

@oskosk mentioned that he will create another PR to address the display of HTML entities within form fields.
