set config to release
initial commit of lua glue trigger module.

While it occurs to me that this might be largely pointless as Lua doesn't have real threads so any watcher will block, and as such a C module will need to be implemented and required by any lua module created, I can still hope that somebody might find this easier than creating an entire C module. 

If not, it only took a few hours to make this, and it was good practice and a good lesson learned, so w/e.

It turns out that pins 8-13 on an Arduino Uno are some non-standard distance from the rest of the pins. As such, making a custom shield for an uno that uses these pins is an sisyphean exercise in futility. Refactored to use pins 2-7 instead
removed load_config
removed load_config from the module API. Config is loaded when the module is loaded, and it has been working this way the whole time.
