Refactor eight-track to use Connection classes for incoming/outgoing requests/responses and fs-store for interacting with storage abstraction

Adding dev notes

Removed dev console.logs and updated last setImmediate piece

Fixed Travis CI again with `async.setImmediate`. This timing stuff is ridiculous.

Tweaked variable arrangement

Deleted dev console.logs and went back to newest async

By deferring the loaded event, everything works for 0.8. Yey

Moved to older async but still no luck

It looks like 0.8 and 0.10 have different behavior for interacting with `end` and `async`

Broke out get/set fs logic into its own file

Cleaning up dev console.logs and `handleConnection` size

Relocating conection creation made things happy

Encountering strange timeout issue with async

Moving to async but it feels like lipstick more than anything =(

Leaving another important TODO

Broke out connections classes into separate file

Staring at code to see room for thinner code

Completed refactor with tests passing

Made distinct classes for incoming and outgoing connections

Patched up refactor to a working state

Creating connection class and relocating all req/res pieces to it

Added TODO note for self

Making an important TODO

Moved to `tee` model for handling response

Tweaking connection model

Moved external request making to its own method

Relocated all request/response logic into instance method

Relocating EightTrack logic into standalone class

Moved from getting/saving responses to getting/saving connections

Updated test files to match new saves

Cleaning up excess data that we resolve

Adding additional info to responseInfo

Relocated info collection into class methods
