[Sablevm-developer] Config File Parsing (Done)

[Brent F. <bfu...@de...>]

I've committed changes that implement a configuration file
parsing system.  It starts at the SYSCONFDIR (which is set
by autoconf), then checks the user's $HOME directory, and
finally it evaluates the command-line parameters.

The parameters observed the following rules of precedence:

1.  Command-line parameters trump everything.
2.  $HOME directory configuration parameters are second highest.
3.  SYSCONFDIR config parametres have lowest priority.

I've tested it on my system, so I'm pretty sure it doesn't
break anything.  But of course, please let me know if you
discover otherwise! ;-)

Thanks,

-Brent
