mount --version pathc

[Joshua Daniel Franklin]

Here is a --version patch for mount.  I also alphabetized longopts,
opts, and the getopt case statement.

ChangeLog:

2002-05-22  Joshua Daniel Franklin <joshuadfranklin@yahoo.com>
	* mount.cc (version) New global variable.
	(usage) Standardize usage output. Accomodate new version option.
	(print_version) New function.
	(longopts) Accomodate new version option.
	(opts) Ditto.
	(main) Ditto.
