Fixed bug with LogoutView.get_redirect_url

Needed to accept **kwargs and pass it on to default_redirect like the other
views and this fixes a NameError bug.
Bumped to 1.0b7
Updated docs for recent API change
Update docs/migration.rst

Add MySql SQL migration.
Fixed recursive import with load_path_attr

account.utils wants account.conf and account.conf wants account.utils. This
commits fixes that by moving load_path_attr into account.conf.

Thanks natmaster for detecting this early in the morning.
Added missing import in account.middleware
Moved load_path_attr before AccountAppConf

This is needed due to AppConf calling methods as soon as the class is created.
Added EmailAddress object to confirmation email context
Call SignupView.after_signup before sending email confirmation

There are many cases where the after_signup hook needs to setup data from the
form that may affect what is displayed in the confirmation email. By moving
the email confirmation send after we call after_signup a site developer can
build a more personalized email confirmation email.
Moved version string to a more universal location
Bumped version for next release
Removed successfully logged in user message

This message isn't entirely useful and adds to the user experience in a bad
way by default. If a site wants to maintain this user message it can be done
with an custom subclass of SignupView.
