3.2. --read-from-file

The Freecell Solver command lines could get very long.
To resolve this and allow for a more modular command line, a meta command line argument was created --read-from-file [SKIP],[FILENAME].
This allowed reading arguments from a text file with a format similar to a Bourne Shell command.
(The code that tokenizes this file resides in cl_chop.c and is quite hideous. Still it works and doesn't interfere with the rest of the program so I just keep it as it is.)
