Line Division, Resources, JQuery.form

Installed JQuery.form where needed for multipart/form-data AJAX.

Successfully implemented get_resource and add_resource. delete_resource
remains untested. Caveat: cards do nothing to display the resources that
they own.

Successfully implemented deck/new/upload_image. Web client does not
interpret feedback yet.

Line division demo visible from index. This can basically go straight
into the create_deck page once I have time.

TODO:

-Fully implement create-deck-from-image
-Fully implement card resources
-Restructure website with frames
-Style (or prepare for Nick to style)

What can be done before the meeting: maybe one of these.
