Update README.md
Fixes a *huge* bug, where we weren't actually saving to/cc/bcc/etc. if the message had more than one address...

Test Plan: just query your db for stuff like `message.cc_addr` to see how bad this bug is :(

Fix remove_messages deletes not cascaded.

Summary:
Deletes were not cascaded i.e. deleting a uid did not cause the corresponding message etc. to be deleted.
This was because of how the Query.delete() works in SQLAlchemy, see: http://docs.sqlalchemy.org/en/rel_0_9/orm/query.html#sqlalchemy.orm.query.

This commit fixes that by using session.delete() instead.

Test Plan: None.

Move misc utils back here.

Separating them out while things are still changing so quickly is too
confusing. We can rip out code we want to share later.
