#29 command-line argument improvements

[Dallen Wilson]

This patch adds support for unix-style arguments, eg '--verbose'. Currently only '-v' or '-verbose' styles are supported.

This patch adds a --help (-h, -help) command to display the program name, version, website, and a list of supported arguments.

Running the program with an unrecognized command will now result in an error message stating such, with a suggestion to try '--help' to get started.

Uploaded an updated version of this patch: '02-command-line-args-improved.patch". Please do not use command-line-args.patch.

Changed priority to 1 - Lowest.

Updates:
Updated some of the -profile code that was missed the first time around.
Handling of arguments that require additional input (a string, a number, etc) is now handled more gracefully if the required input is omitted.

The patch was written using svn rev 2890 as the base.
