Added initial collect code
Merge branch 'devel' of github.com:abreen/socrates into devel
Added functional version of collect mode
Fixed collect bug, added --ws-name option to collect
Changed collect mode to WebSubmit mode, completed features

WebSubmit mode now prompts the user for an assignment name and
course name known to WebSubmit, and uses this data to create
a directory ready for upload to WebSubmit.

WebSubmit mode draws directly from the dropbox used by graders
and takes the most recently submitted grade file from each version
(if there are more than one) from each group in the dropbox.
Added --activity flag to WebSubmit mode

The --activity flag allows coordinators to see when graders submitted
grades, and for which part.
