Allow # for Comment in username file.  Add Try/Catch to catch ValueError if user not found.

1) Add a split for the username file to allow # to be a comment
character.
2) If a user was not found, a valueError exception was being created.
The higher level code was not catching it, and causing the app to
crash.  Added Try/Catch to consume the error and output a warning.
