Issue

Closes #32

Description

We released without the renderer being finished, and so there were multiple display issues with displaying help content, particularly in tables. Also things like, if NO_COLOR is set, we don't just skip color, we skip any terminal code.

Now, the initial renderer has been finished, and lots of 'features' have been added, for instance, to allow us to have more flexibility in table layout.

There's a default chalk 'style' too, but it's set up to make it easy for us to enable others to configure their own style.

The renderer is 'good enough' now that we will have a very easy time moving to any sort of full-screen model instead of a scrolling model... which I do intend to do soon with the component system.

However, now that things seem pretty healthy, we do need to go back and adjust the docs to format properly. I've seen there are definitely some places where tweaks need to be made, for instance, if the doc is using markdown in a context where markdown doesn't get processed, etc.

Testing

Try chalk help or chalk help metadata and see that they're no longer utterly horrid.

The failing tests are only failing because of error message changes in Con4m and will be passing as soon as #47 is merged.

All looks good to me
