Notes on upgrading from Camas 1.0 or IMHO to Camas 1.2
======================================================

Camas 1.2 has a lot of differences with previous version.
While we tried to keep the maximum compatbility there are
some steps you will need to do in order to upgrade:

o The Incoming mail server (IMAP) is not anymore in
  Camas main module but in one of the Auth module you
  use (by default it is Camas Auth Basic)

o The layout sub-system has been completely re-written. 
  Your old layouts will be keep by default as well as the
  default blue one. If you want to try the new default layout,
  remove the module named "Camas: Default IMHO layout" and
  restart the server.
  If you don't use the Camas 1.0 or IMHO layouts, you can
  safely remove the modules "Camas: IMHO Screens" and
  "Camas: IMHO Tags".

o The location of the preferences folder has changed. 
  It is now in the "Camas: Preferences IMAP" module 
  instead of the Camas main module.

o For performances reason the size of the folders is not 
  fetched at startup but is either:
    - Set when the user goes in the folder
    - Set by the background IMAP cache feeder at startup if
    you enabled this option

o The quota mecanism has been removed from the Auth modules since
  Camas now support quota from the IMAP server which is a better
  way to support quotas. A side effect is that users of Camas Auth module
  must set again their basedn and filter in Webmail names

o Configuration variable Camas Main module -> Outgoing mail -> Sent message
  notification is gone in flavor of Camas Main module -> Misc ->
  User interface: Display SMTP confirmations to user.
