Make course title wrap when displayed on home (set to wiki page)
Make course title wrap when displayed on home (set to wiki page)

Chose to wrap instead of truncate because long assignment titles
wrap and syllabus home page title also wraps.

Fixes LS-1271
flag = none

Test plan:
 - Create course with really long name
 - Make a wiki page and set it as the front page
 - Set the course home page to be the wiki front page
 - Go to course home, expect course title to wrap and not run off
