Fix review form after Bugzilla 4.2.5 update

Fix review form after Bugzilla 4.2.5 update

* code-review.js:
(fetchHistory):
- Trim author since new format adds a space before the name.
- Update comment_marker to match the text now used by Bugzilla.

* template/en/custom/attachment/reviewform.html.tmpl:
- Add global/header.html.tmpl to make sure we get the standard
  HTML for including CSS, JavaScript, etc.
  - Remove redundant <link> tags.
  - Add CSS in local <style> to hide the header.
  - Change local <script> to be passed as an argument into
    global/header.html.tmpl when it is processed.
  - NOTE: local <style> tag should be passed as an argument into
    global/header.html.tmpl, but that breaks page layout, so it
    was skipped for now.
- Fix fallout form moving flag_types into the attachment object
  when processing flag/list.html.tmpl.
