Recursive require refinement

[wied03]

Might need to make code in rack_server recursive for this to work. Depends on if Sprockets returns back immediate includes or nested ones. Could add a test that does nested dependencies. We would want to check 1) that everything functions, 2) that the metadata includes the correct stuff and 3) the JS doesn't include what's already split out.

Might want some MRI tests that cover getting dependencies out of Sprockets and some integration tests that hit a running Karma instance.

sprockets_env.find_asset(a,pipeline: :self) to serve up assets only

Still need to make the default_path adjustment

Main todos:

• Figure out how to replicate the last commit in a test
