Corrected the d2l_offering view. It was assigning (doc['type'] = 'course') instead of comparing (doc['type'] == 'course').
Re-added the if statement to only process lectures and seminars in the d2l_offering view. It was accidentally taken out in the previous commit.
Added a basic implementation of couch2d2l that can write files and upload to the holding tank.
Added .alldone file generation for upload to holding tank.
