Change default class to abstract

[teror4uks]

Good package for simple logging, but sometimes in model StatusLog need new field and this very difficult in current realization. Maybe good idea store in package only abstract model? And If you want using him in your project you must implementing user class StatusLog which inherit abstract model from a package like this:

from django_db_logger.models import  StatusLogAbstract
class StatusLog(StatusLogAbstract):
    new_field=models.CharField(max_lenght=100) # or for basic fields just write `pass`

After that get new migrations and that's all changes.
