Updated help text and added commit ID to the version information

[mike632t]

See what you think.

Note - To save disk space removed the test programs so you may want to be selective when merging these changes.

The help text has been reworked slightly, and I changed the error messages to use a display a brief message describing the command usage.

Two new command options (-? and -V) can be used to display the help test and version respectively and the code now checks for the -C option before converting the options to lower case.

The commit id is generated using the command git log -1 HEAD --format=%h when the code is compiled.

The automated build in github using mr.bat is failing with invalid command. Can you please take a look and resolve this? Thanks! The other changes look good.

Not sure if I have fixed it (I don't actually have a Windows machine I can test it on) but it says awaiting approval so I think it has got past the automated build test?

Hmm. Failing in a new way now.

I'm afraid I've given up trying to pass the commit id from a batch script as I can't test it. I think that COMMIT_ID is being defined but does not have a value. As a result there are not enough parameters for the printf() statement...
