[PD-dev] New [command] external

Hey all,

I am recently trying to dive into the C realm and revamped ggee's [shell] external. Because its API is different in many ways from the original, I decided to give it a new name.

Before I publish this to a wider audience through Deken, I would like to make sure I do not destroy the world by releasing this. Any comments or suggestions are welcome.

A first question I have is concerning the order of outlets. I kept the original order: STDOUT left, exit code right. However, since the exit code outlet fires always last, it probably would make sense the make it the left-most. Are there any similar precedent objects?
