Added sf\3tshell platform with support for building beagle textshell+fshell ROMs. As part of that: * Added baserom command and tweaked it to be more friendly with SF baselines. * Lots of build fixes Also cd now makes sure the current working directory matches the file system with respect to case.

#!/usr/bin/perl

# This is a script for removing trailing whitespace from lines in files that
# are listed on the command line.

# This subroutine does the work for one file.
