First stab at a solution
Add test for logging via psgi env
Dont add \n for psgi logs(?)
Add some description to the test
Don't store the entire psgienv, just the pieces we need
Make the methods "private".

This is to discourage usage by others for now.
Add pod for the external method 'psgienv'
Change PSGI tests from subtests to blocks

To work with Test::More 0.88, which is what catalyst requires.
