Unbreak QueryParser.parseModels()

My last commit here (https://github.com/hypothesis/h/commit/5f56d8ad0424f11e52736fd9a1f9b8c30ab0f6a1)
has broken this function for or operators, because it forgets to apply the rule.format() call
to the search terms

I.e the user field uses this to transform the username to the full user format (acct:username@domain)
And because of this the user streams were broken.

Fix #1391
Reposition lock icon in editing interface. Add icons for privacy options. Remove unused CSS code.
Add selected class to currently selected level in the privacy dropdown.
Add focus state to buttons. Add outline:none; to .form-input:focus and clear:both; to .formfield.
Make grey default background-color for inputs. Kill bold on the privacy drop down.
Drop heatmap comment tab and convert tabs to css

Kicking off work on revamping the heatmap a little bit. This change
removes the comment tab. Clearly, something needs to be done to restore
discoverability to comments, but there seemed to be some consensus that
the comment tab was not comprehensible enough.

Additionally, I got pretty sick of the tabs bouncing around. I removed
the transitions, slimmed the tabs down a litle bit, and remade them in
pure CSS. The pure CSS has the advantage of avoiding extra network
requests to fetch the tab SVGs. Also, the SVGs contained some padding
and borders that is easier to account for if its all in the CSS.
Use non-mixin border-radius everywhere
