Merge branch 'master' of github.com:dellsystem/wikinotes
Remove call to page.load_content() in page views

It's not needed now that all pages have something in their content

This also ensures that the tests work without having to mock anything.
Update titles for some course-related views
Remove unnecessary server_url in printview context

Not needed since we have {{ site_url }}.

This also makes the test work without having to add a meta variable.
Fix 'hash' context variable in commit view
Add TODO comment to hardcoded URL in gitutils.py
Call page.get_repo() in page history/commit views

The method has existed for a while, dunno why it wasn't being used there
