* Added support for migrations
* Big refactoring of the admin code
done: Support for SHA256 algorithm to store passwords (fix#195)
done: admin models refactoring (fix#196)
* We now make a difference between users that own a specific object and users that have access to a specific object
* Limits are not moved anymore (from one reseller to a domain admin) when we grant access to a domain
see #105
* Demo application : set the managesieve authentication mechanism to 'PLAIN' by default because the dovecot version provided with Debian squeeze is a buggy one.
new: parameters module refactored. The API is more simple now, there is no need to provide a module name anymore, this last is automatically guessed. Also, a new 'label' field can be provide when declaring a new parameter. It will be used instead of the name.
new: email parsing refactored. My first attempt was really ugly. I did not really studied the various RFC describing how messages are formatted or what IMAP fetch queries can do. Now, I hope this new code will face better unknown types. At least, It will be simpler to update.
wip: #36, using tinyMCE (django-tinymce) to write messages in HTML. Currently, compose a new message is working pretty well. Answering or forwarding a message is still a mess...
