wip: allow complete motion customization

[willothy]

This will allow for integrations with things like nvim-spider. Not sure how I feel about my current API. Very WIP.

I'm not sure about this API design

I think that basically all these plugins do is reimplement the cls() algorithm

So I think we could just provide a method (metatable probably) to override that with a custom function if set

Yeah I agree, I'll think about a better way to design this. This was mostly messing around with the idea.
