A few notes:
1. Downloads are done through direct requests.  This is due to the difficulty of downloading a file to the correct place
2. Modifiying a file will just change the file to a random 10 character string.
3. The page is reloaded in between uploads.  This is due to a current caching bug that is in the process of being looked into and will be updated once it is fixed.

% to format
css_find().click() to its actual function
A few name changes as well as step changes
Removal of drag testing
A refactoring of login and create user.  Login will no longer create the specified user

Also added in drag and drop helper.  Please be careful using this method as it is truly a hack to obtain the visual effects.  As of this commit, selenium does not support drag and drop for jQuery sortable items

TODO: When deleting is available, test deleting uploaded files`

test.py was changed such that the database being used is test_xcontent
course_helpers.clear_courses now calls contentstore().fs_files.drop() such that all content is removed and the databse is started afresh in the same manner as the modulestore

Also modified the create_course method in common to allow for the possibility to access the course name and etc. from other files.

set to True and a SEGMENT_IO_LMS_KEY is set.
