Switched to node-powered build script.  It's short(ish), sweet, and does
everything the build.sh did, but more cross-platform and robust
Set main module in package.json, so you can now require('angl') instead of
require('angl/out/angl')
More build script cleanup
Merge branch 'master' of git://github.com/cspotcode/angl
Fixed windows compilation!
