* Added 'UserSettings' model to provide a user profile system independent of existing Django user profiles, for two reasons: 1) Avoids users having to update settings.py and 2) Allows jutda-helpdesk to integrate with websites who already use a User Profile
* Settings added in this revision allow a user to control e-mail alerts, and to determine whether they see the dashboard or ticket list at login.
* New 'Settings' link in page footer for signed-in users
* Logout now takes you to the Helpdesk homepage
* Fixed file attachment bug in management/commands/get_email.py which seemed to have been un-done (fixes issue # 4.
Jutda-helpdesk is now compatible with Django 1.0!
