Initial commit for the wedding branch

* Started the wedding app. Doesn't do much yet.
Added Wedding app and some minor other tweaks

Minor Tweaks:
* Added CSS (gallery.css) to display thumbnails for wedding pictures
* There are some changes in the basefunctions/views.py that were to test the
  {{next}} feature for logins. This is NOT done, only comments have been added
  for tests
* LOGIN_URL in settings set to /login

Wedding App
* Started the app
* Started the gallery template
* Added root and gallery to urls
* Added a model for each picture and the model admin
Updated the wedding app and some custom tags

* Added a gallery page to the wedding app. Needs work: pagination,
  thumbnailizing, and testing with images
* Added the gallery to wedding/urls.py and made the gallery view
* Added a img_link tab - not good this is a hack. Needed for testing. Can
  stay.
* Updated gallery.css to add cell padding to <li>

Still have not merged the wedding branch into master.
