Michael Schuett ff1c0b58dd Start of category flag support
This adds what I think needs to be done to support categories for flags
but we will see if that works. It also forces the scripts to use python2
since they blow up under python3 which is becoming the default python on
many linux systems.

Small fix to app_test as well so it conforms to the new Flag interface.
