Put all generated types under a "types" directory

[pmcelhaney]

A fairly simple change:

• path-types -> types/paths
• components -> types/components
• paths -> routes

I think it will be easier to understand what's what. The structure of the types directory should resemble the structure of the OpenAPI spec. And "routes" is a clearer indicator of what the directory contains.

I don't like to catch people off guard with disruptive changes like this. If we're going to do it, it should be before 1.0.

Maybe there can be a grace period with backwards compatibility. If a paths directory is detected, Counterfact will continue to use the old structure but print a warning with migration instructions. (It's a matter of renaming a couple of directories and then doing a search and replace.)

I do think the renaming is better. Not so worried about the breaking change, pre-1.0 but rather than supporting both, what about a migration script that just moves everything to the new places?

[pmcelhaney]

Could write a migration script. I just don't want to inflict unexpected changes on people.

After 1.0 I'm going to start promoting. I'd rather get this sort of thing out of the way before more users come.
