style(Faculty Journal): remove italics, bold title

Fixes: UIDEV-205

test plan:
- click admin from main nav (select main acc - not site admin)
- is there a 'Faculty Journal' option in the sub-nav... if not
  the feature will need to be turned on via checking the box
  on the first tab of the settings page
- once or if it is available select 'Faculty Journal' from the
  sub-nav
- create an entry ... ensure the title has been bolded and the
  author and time stamp are no longer in italics
