Extract from Stockor into Lanes framework

This extracts various parts of Stockor into a new framework that I'm
dubbing "Lanes".  It has parts of stockor-core, api, access, and
workspace.
Lock gemspec versions
Remove unused sass css importer
Add generators for creating app and models

New commands:

Spec helper for apps
Better help messages
