[saily]

- Reverted changeset 119773 since users could not send folderish content
types any more (RichDocument is a folderish content type).

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

- The send form is now split into two subforms, one for send, and one for
preview. **NOTE!** This introduces incompatible changes if you are having
custom forms (although the changes necessary are simple).

default.

- Changed all occurences of site-title to site_title (in help strings
and translations).

- We now avoid including all zcml from five.intid (in the same way as e.g.
plone.app.intid) This means we avoid registering the IPersistent handlers,
which (among other issues) can cause problems for packages that put persistent
items in temporary storage. Instead we explicitly register handlers for
ISubscription. The issue is discussed here:
http://www.mail-archive.com/zodb-devzope.org/msg04398.html
And at length, as pertaining to the getpaid package, here:
http://code.google.com/p/getpaid/issues/detail?id=209.

- Reverted changeset 113529 since it broke subscriber searching (and tests).
The revert has likely reintroduced a problem with deleting subscriptions,
but I've been unable to reproduce this.

- When importing email addresses, convert all addresses to lowercase
instead of rejecting them.
