Added missing rendering XSLT match for 'th'
Removed some left-over refs to AuthorMode.js
Merge branch 'master' into lti_iteration_2
Fixes to LtiOutcomeService:

* Added oauth_body_hash, explicitly computed.
* Better setting of encodings
Minor tidy of recent LTI functionality
Tidied up LTI dashboard
Continued tidy; fixed some routing regressions
Simplified assessment name/title properties

Nobody was ever changing these, so I'm removed from the MVC layer,
removed the name property completely, and moved title to
AssessmentPackage.
Ported new Assessment Library JSP to old MVC
Ported new DS MVC over to old instructor MVC

(This was a regression in DEV31. I have tidied things up slightly
in both interfaces.)
New layout for LTI "show assessment"
Minor tweaks after recent commits
