Fix settings variable 'PIPELINE' to 'SOCIAL_AUTH_PIPELINE'

[paulsoh]

Changed variable name to be more specific.
'PIPELINE' variable is also a settings variable used in django-pipeline, which causes an error when used together. #838

You can already just use SOCIAL_AUTH_PIPELINE and it should work...

@webjunkie Thanks for proving my point.

The default namespace PSA uses is PIPELINE which causes an error when used with django-pipeline, (django-pipeline also uses PIPELINE) and as you said if you change it to SOCIAL_AUTH_PIPELINE for PSA there is no conflict between these two packages.

Thats the reason for this PR, I changed the default PIPELINE to SOCIAL_AUTH_PIPELINE.

@paulsoh You did not get me right. There is no use for this PR as the default is already SOCIAL_AUTH_PIPELINE. The self.setting() method in the same lines that you want to be changed automatically prefixes everything with SOCIAL_AUTH_ and at least for me, I just use SOCIAL_AUTH_WHATEVER in my settings and it works without conflicts.

python-social-auth will try several setting names in the following order:

• SOCIAL_AUTH_<BACKEND_NAME>_PIPELINE
• SOCIAL_AUTH_PIPELINE
• PIPELINE

The utility setting_name in utils.py adds the setting prefix SOCIAL_AUTH_ to the names.
