Add generators!

[Bishwas-py]

Adding generator would be an awesome and fun task to do, also a very useful thing for the project:

Samples:

Gen model

djapy gen.model user:fk:django.contrib.auth.models.User body:text title:char[max=225] slug:depends:"{title}-{id}"

Gen views + model

djapy gen.app user:fk:django.contrib.auth.models.User body:text title:char[max=225] slug:depends:"{title}-{id}"
