create-dev-env.sh:  if run from repo, set $BASE appropriately

2 changes:
[1] If PROJECT_HOME is not set, AND create-dev-env.sh is run from a cloned repo, then set BASE to that repo;
else:  (and only finally) set BASE to a default of "$HOME/edx_all"

[2] if PROJECT_HOME is set, or if this is from a repo, don't add edx_all to the BASE name (no need;)
Moved from djanalytics to edinsights
Started removing XML from video editor.

TODO: This breaks the 1.5x and .75x speeds. I'm still looking into
why.

TODO: VideoDescriptor inherits from RawDescriptor in order to
use the from_xml and export_to_xml methods. This seems really ugly,
though; I'd rather find a better way to do this.
analytics server setup simplified
simplified analyticserver settings
simplified analytics conf
Fixed .75 and 1.5 speeds playing at 1.0 speed.
Changed description of source and track fields.
Added testing for grading settings

Please note that 2 tests will not reliably work:
Deleting a grade- Was able to circumvent this with javascript
Moving the grade slider- Could not circumvent, is skipped but the framework is in place
Added in testing for course team

Also modified the create_course method in common to allow for the possibility to access the course name and etc. from other files.
Tests now use their own contentstore database

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
Fix failing acceptance tests and allow videos to be imported from XML.
Added tests for uploading files

TODO: When deleting is available, test deleting uploaded files`
Removed test breakpoint
Added in the drag and drop support
Enable exporting video to XML for backwards compatibility.
