OS.js Lua HTTP Server Setup

OS.js Lua HTTP Server Setup

Just quick and dirty instructions on how to run the Lua server on OS.js. Since this runs natively on arduino via build scripts originally -- you have to do some manual wizzardry.
# Files

They are located in the arduino build: https://github.com/os-js/OS.js/tree/arduino/src/server/lua

1. `osjs-api` This is the API endpoint. Place this as `osjs/dist/API`
2. `osjs-fs` This is the VFS endpoint. Place this as `osjs/dist/FS`
3. `osjs.lua` This is the OS.js server script. Place this in `/usr/lib/lua`
4. `session.lua` HTTP Session Library. Place this in `/usr/lib/lua`

# Dependencies

These can be installed via opk

1. `luci` - The 'JSON' library was taken from this package
2. `nixio` - The filesystem abstraction
3. `wsapi` - The HTTP abstraction
4. `uhttpd` - The Webserver
5. `lua` - The Server runtime. You probably also need the CGI package for uhttpd to work

# uhttpd

Set uhttpd to serve from `osjs/dist`
