Removed debug output
Updated jquery 2.0.3->2.1.1
Adjusted all our scripts to "use strict";

- A big part of our website is written in JavaScript now.
  By using strict mode we reduce the mistakes possible in the code,
  because it becomes easier to trigger syntax errors or throw exceptions.
Moved contents from /website/main to /

- Before publishing this repo on github there used to be other directories parallel to website,
  which made it useful to have the website stuff in its own directory.
  But now that this repo is concerned only with the website,
  it's logical to have the website reside at the toplevel.
Updated README.md with further setup instructions
Bugfixes for strict mode.
Implemented default cases for collections/{Choice,Selection}

- Until now it was possible that Choice:setChoiceByKey or Selection:setSelectionByKey were fed with invalid keys,
  for example when the study was changed and old keys remained in the URL, or when the user enters invalid URLs.
  To mitigate this issue both methods now check for cases where the key can't be found and revert to defaults in that case.
Bugfix in Language:getSuperscript
Bugfix in Region:getColor to obey Study:getColorByFamily

- Region:getColor now returns getFamily().getColor() if the families color should be used instead.
Bugfixes in {Map,Word}View for cases where no Transcription is found.

- In such cases we now simply don't try to display content,
  but we might also like to throw exceptions or at least log messages,
  to raise awareness for missing transcriptions.
