Removed references to user/group robot from setup script and debian postinst script so that they can be run on non-Barrett hardware, and can be accessed by all accounts on the PC.
What to focus on
I just deleted the chown from both scripts which results in all /opt/barrett/burt files still being owned by root. I also tightened up the permissions from 777 to just read and write, since that's all that's actually needed. Execute privileges for /opt/barrett/burt/bin get set elsewhere so I don't think I need to worry about that here.
This is obviously just a personal pet peeve, so no rush on the review here.
