Granular/scripted control over LEDs

[philpax]

Currently, Borealis only allows users to set the entire system's LEDs to the same colour (specified via CLI). Ideally, more granular control would be offered, including being able to control individual controllers and LEDs.

Additionally, given that people love their RGB animations, some kind of animation or scripting interface would be good. I'm thinking Lua; I've been looking for an excuse to play with rlua...
