Nicer help message about scc

[boyter]

I will admit copy writing is not my strong point.

I will have to see about wrapping. Its done though https://github.com/urfave/cli and I don't remember a way to do it in an automated way, but perhaps newlines will work.

If you want to submit a PR with redone messages id be happy to merge it in. Otherwise I am afraid my best guess might still be awkward.

Let me know either way and ill look into the wrapping.

[boyter]

Have modified some of the copy as suggested. Not sure if I can modify the wrapping, still investigating this.

[porglezomp]

That's a lot clearer. The only big issue I still have with it is for --cocomo which looks like it didn't get an update. I'd just write that as "Remove COCOMO calculation output"

[boyter]

Dammit I had a feeling I might have missed one. Ill update that as well.

[boyter]

Done.
