NOT WORKING: refactoring conf logic
Revert "NOT WORKING: refactoring conf logic"

This reverts commit f2d1d0ebae9c73f5789ac475bc2e7c6e7e31a43f.
fix bug in the authRoute function
nodeEnv -> combinedConf
createDriver() now takes a map not just a port_ value
load conf from conf/<conf-name>
do not overwrite original process.env
specify a PORT value in the default object
get rid of the (second, obsolete) default port setting
add a test conf; require the conf to exist
early exit if no port
add a prod. conf.
