Improved --help and added --version

Browse source 
I added a --version longoption that says some stuff about the version and the copyright and the people who made mkp224o,

Also,

I made changes to the helpfile:
~ It now fits in small terminals that are 80 chars wide without being screen wrapped
~ It looks pretty like GNU utilities now
~ It has a couple less typos
~ It now has a link to the mkp224o homepage and a link to the issues page
~ And it now mentions the --help and --usage longoptions (and also the new --version longoption that I added)
