Multiple thumbnails

[byashimov]

HI!
Running Django 1.4 with django-filebrowser-no-grappelli trunk.
After an image upload filebrowser creates several thumbnails of it and puts them in the root directory, that makes filebrowser do thumbnails for thumbnails and thumbnails of thumbnails on page reload.

This makes filebrowser store images in separated dirs:
DIRECTORY = 'uploads/'
FILEBROWSER_VERSIONS_BASEDIR = 'CACHE'

But I guess that's a bit silly :)
