Move node_modules/_app/ into lib/ as a package (#190)

Move the contents of node_modules/_app into lib/ as there shouldn't be
any content in node_modules.  This directory is automatically managed
and pruned by npm.

Add lib/ as a local package in package.json, this allows scripts
everywhere to require it's content as "lib/path" instead of relying on
local paths.  This shadows the StdLib Node.js Bindings package, but I
could care less.

Change all requires with lib as a local path and _app to use just lib.
