https in trackable url

[lcd1232]

Right now if you're using https on server you still get url with http, there is no checking about protocol.
Problem is here

I think we can add new constant to fix this problem.

@gotlium I think better provide argument like is_secure or the whole request object to def send_db_mail(*args, **kwargs) because one django server can serve many sites and some of them can using http and others https. The best way to know is https or not using check request.is_secure()

[gotlium]

By default we can use is_secure=False, and when required https, developer can add is_secure=request.is_secure(). PR?

@gotlium yeah, will do
