Add missing profile symlink
Wrote database_list and added appropriate __main__ method
modified help to include 'list' command
Don't return "disabled" databases

The old PHP interface didn't drop rows when the database was deleted,
it merely set bEnabled to 0. Account for this when reporting a
result. (Additionally, remember that there's a DBOwner in the path and
access the .Name and .nBytes variables appropriately.)
Removed remnant sys.exit line
