[Respin] remove default indent

[Lewiscowles1986]

This is my attempt to re-offer the removal of default indent.

Because it bumps the package version to 2.x, it should protect folks using package.json in a normal way, which I'd define as exact dependencies, or tilde prefixed, so that patches can be applied, but not major versions.

I Also added a note on how to overcome the breaking change if that is the desire.

I Felt bad for making a comment that got someone else work removed without discussion. The first commit is their patch applied to the latest master.

I Couldn't get that verb cli working so I merely applied some markdown changes to the repo.

Changes:

• re-applied patch to master (ran npm test)
• bump version
• improve documentation

@Lewiscowles1986 I appreciate the contentiousness about removing another persons work that drove you to make this PR. I have no particular knowledge of this package, but I wanted to give you some deserved Kudos.

Thanks @Lewiscowles1986 ! I'll get this merged in soon.
I'd also like to do a couple of other breaking changes, so this will be released along with those.
