Django-encrypted-fields

- Fixes `SubfieldBase` deprecation warning.
- Added new EcryptedDateField class
- Fixes 7 & 13

A small fix for Python 2.6.

- better unicode support
- MIT licence
- a bunch of features from Eventbrite

I admit, the 1.0 is pretty arbitrary. It has seemed really stable though in all the cases I've been using it.

I also added `EncryptedBooleanField`.

- Added EncryptedEmailField
- Fixed a timezone warning when running the tests in the Django project with L10N

Added `EncryptedFloatField`
