don't titleize wiki page titles in wiki sidebar
don't titleize wiki page titles in wiki sidebar

test plan:
* create a wiki page with a name with several
 capital letters together (e.g. "FAQs")
* when editing/creating future html content,
the link to the previous page in the wiki sidebar
should match the title (e.g. "FAQs" and not "Fa Qs")
