throw exception when key longer than 64 characters

I added a check on the length of gargoyle keys, this will prevent problems on SQL-databases with 'Strict SQL Mode' disabled.

Hi @switch87 , we considered merging this into the YPlan gargoyle fork, however because MySQL has many problems without strict mode active, and this only fixes one such problem, we don't think it's worth merging. Please check out my package Django-MySQL, which has a number of Django + MySQL improvements, including a check that recommends strict mode, plus a guide on how to activate it: https://django-mysql.readthedocs.org/en/latest/checks.html#django-mysql-w001-strict-mode .

Thanks!

@nielsvanoch Django-MySQL is misschien wel interessant voor jullie, dit gaat nog over een probleem war ik bij jullie op gestoten was.
