Log Message:
Limit User Folders

A user managed to synchronise our server with their UWash IMAP
server's view of a very busy home directory, creating tens of
thousands of folders and showing that there's a DOS risk against
mailboxes.db here.

This patch creates a new config variable user_folder_limit which,
if set, returns IMAP_PERMISSION_DENIED to any further attempts to
create a folder if the user has too many folders already.
