Setup asks for S3 credentials, even if set with env variables

[boomam]

Hi,
Current release of 1.8.1, setting of the S3 related environment variables listed here do not get set in app, requiring manual input during the setup wizard.
I am not sure if this is a bug, or if its a fall back for the CORS bug, happy to help investigate though.

Thanks.

Thanks I'll look into it

...to expand on the comment in the other issue (#72), im wondering if it is setting, just maybe falling back and showing the options in the wizard.
As after a little time, i can see the uploaded files within the s3 bucket.

I changed how the setup handles env variables in 368fb6b. If that does not fix the issue, let me know and I will reopen it.
