Rethink how smartparens is used in normal state

[PythonNut]

I think the current setup is suboptimal on several counts:

Using the prefix gs means there's too much "warmup time" before the hydra can come in and make things efficient.

Also, on-parens has a movement model that closely maps to evil words. It might make sense to use bindings that rely on this correspondence more. This might finding someone else who uses it to see what they do...
