Issue #5: Created a whitelist, made AMPSystem_Upload use it for uploads
Merge branch 'vulnfix'
Merge in master and 7-get_unit_test_suite_back_up_to_par.  We are keeping Saras version of Upload.inc.php, but will make some minor changes to it
We are no longer supporting the upload of videos.  Also changing the mime-type for wav to audio/x-wav
This gets the units tests for file uploads to exclude video uploads.  All tests are passing.
