Password-Reset-Links are not working

Hi,

while trying to set up a brand-new project (django 1.6.2, mezzanine 3.0.9), I realized that password-resetting doesn't work.

In django1.6 the url-parameter for reset links changed from encoding the uid as base36 to encoding it with base64. Of course they had to change the keyword-name too.

While the fix in mezzanine seems easy enough following the instructions at https://docs.djangoproject.com/en/1.6/releases/1.6/#django-contrib-auth-password-reset-uses-base-64-encoding-of-user-pk, the template for the reset-mails in grappelli-safe has to be changed as well.
