Support loading from NODE_PATH, fixes tkellen/node-liftoff#28

[Meroje]

This will pass NODE_PATH to resolve.sync when looking for the module to require, or empty array if undefined (default for most people) which behaves the same.

Fails on windows because of this: .split(':')

Example path: C:\Users\IEUser\Desktop\GitHub\node-liftoff\explicit\cwd

I'm conflicted about including this. It really belongs in resolve, but @substack refused a PR adding support for this here: browserify/resolve#47

Any thoughts @phated?

If we have to use substack modules, then we should handle the case in our lib. Just make sure it works cross platform

Note: On Windows, NODE_PATH is delimited by semicolons instead of colons
