feat(ao-cli): ao build accept multiple files #120

[twilson63]

This PR, updates the build script to support adding multiple lua files to the wasm process. Since the compiler is running inside docker you have to require your files using the convention that they will be bundled. All files in your current directory are located in the /src/ folder of the docker container.

To properly require you files, you need to do the following:

local foo = require(".src.foo")

In lua, the dots represent slashes, so "/src/foo.lua" is represented by ".src.foo". If you create a folder in your dev environment, then you will need to create that representation in your lua file.

File: /src/lib/bar.lua

local bar = require(".src.lib.bar")

Nice, LGTM.

This looks to be backwards compatible because loader.lua requires .src.contract then invokes handle exported from that module. That module can require as needed.

So since that module will still be included in the bundle, we should be good?
