Title: Read vendor packages from the vendor directory

I'm pretty sure I haven't implemented this correctly but I find it pretty convenient to include vendor libraries in my application's vendor directory. I know this isn't the recommended solution but it is simple and serves my needs. I use this to support node-canvas which requires cairo.
