------------------

- SearchableTextExtender: For mails with incorrectly declared charset,
try decoding them as latin1 as a last resort, ignoring all errors.
[lgraf]

- SearchableTextExtender: Don't just decode the Content-Transfer-Encoding,
but also decode the actual content itself with the declared charset.

------------------

- Fix brown bag upgrade step from 2.2.0.
[jone]

------------------

- Performance improvements:

- Store the title from the mail subject on the object, so that
we don't have to read the message for retreiving the title on access.
- Cache attachment infos on mail object.
- Cache headers for tabbed view.

[jone]

- Make sure only a *default* value will be set for IMailSettings.mail_domain,
but an existing value won't be overwritten when running the upgrade step twice.
[lgraf]

------------------

- Inbound view: Adapt container as the context instead of content when
looking up default value adapter.
[lgraf]

- Inbound view: Remove AQ wrapper when setting default values for newly
created objects, in order to not get bogus results (due to acquisition)
when checking whether a field is already present on the object.

----------------

- Make mail tab date parsing robust.
[jone]

- Disable sorting in mail tab for header information columns.
Sorting header informations does currently not work because
the information is not in the catalog.
When doing it outside the catalog we could run into performance
issues when we have many mails, therefore we disable it for now.
[jone]

- Use plone default classes for table styling.
[Julian Infanger]

- Fixed response content-type in inbound view.
[lknoepfel]

- Revoke "ftw.mail: Add Mail" permission.
This permission makes the "mail" type show up in the add menu.

Also change the lawgiver hint to ingnore this permission.
