* Use `page-title` to avoid a border on the page header which clashes
with the bootstrap well
Cleanup grid classes on user search

* Remove grid wrappers
* Move sidebar and well styles out of grid wrapper to prevent clashes
(form was expanding beyond the col-md-2 width)
Remove grid classes from parts form

* `col-md-12` is unnecessary as form inputs expand to their full width
in bootstrap 3
