[skip ci] option?

[sarbbottam]

Wondering if it would be useful to display a conditional prompt for docs & chore to add [skip ci] option.

I guess most of the time a build is unnecessary for chore and docs changes.

I like this idea. I want our commit types (see #29) to be deterministic but to still allow for the flexibility of requests like this one. For this reason I don't think JSON is going to be a good enough format for our types. I'm thinking we need to use a type system more like the one in GraphQL.
