Use proper in-line import in Request helper.

Added sendNewRequestNotification to the Notifications helper. This method will send out a notification upon arrival of a new Request to all users who have an active role for the Request's scope and the roles as specified by the getRoleLogicsToNotifyUponNewRequest. Also renamed getRoleLogicsToNotifyUponeNewRequest to getRoleLogicsToNotifyUponNewRequest.

Added template for a notification upon arrival of a new Request.

Tables listing Requests now show the name of the Group the request is for/from.

Added missing role_name to org_admin Logic. Also reordered keyword arguments in role Logics.

Added getRoleLogicsToNotifyUponeNewRequest for use with notifications. This method returns a list of all the Role Logics that can be used to query who should receive a notification when a new Role Request arrives.

Use proper in-line imports where possible in the Notifications helper.

fix for issue 653 by adding wrap=hard attr to textareas for surveys

seed_db now creates fixture student project entities, and corresponding project surveys and grading surveys for debugging purposes.

Use role_name where needed for creating/handling requests. Also added TODO to extend the redirect for further use with the new module system.
