Remove duplicate package django-stripe-payments

[wolph]

The package django-stripe-payments: https://djangopackages.org/packages/p/django-stripe-payments/
Has been renamed to pinax-stripe: https://djangopackages.org/packages/p/pinax-stripe/

So the old package needs to be removed. Ideally djangopackages should detect these types of duplicates (the github repo redirects) and remove them automatically.

draceditor has also been renamed to martor. And I think there are lots of other packages with similar case.

The auto-detection idea from @wolph sounds nice. Or maybe provide a way to remove a package manually (we can't do that currently can't we?). I don't know which one is better/easier tho.

We have some backend support now to mark a package as deprecated by another package. The front end puts a banner up which should make it more obvious too. We don't have a frontend tool yet to let people mark these (at least outside of the Django Admin.

See: https://djangopackages.org/packages/p/django-stripe-payments/

and: https://djangopackages.org/packages/p/pinax-stripe/
