MailboxHandler.php:

add everything for editing a mailbox

Details:
- include 'maildir' in "display in list" for now (not really
  needed/wanted in listview, but needed for the postedit hook)
- display max. allowed quota in quota field description (via init())
- add read_from_db_postprocess() - convert quota to MB and store the 
  original value in 'quotabytes'
- add setmore() - convert quota from MB to bytes
- add storemore() - call mailbox_postedit()
- add _field_quota() - quota validation
