Allow layout saving loading

[wayofthefuture]

Wanted to get your thoughts on this. After you drag all of your modules around to organize them, you can save the layout, and reload for next time. So as time progresses, I can continually organize the modules, otherwise, the random generation isn't really usable long term. This way it can save / load the layout... using a save button and an extra -l command line option.

LGTM!

We should probably aim to move all dependencies to NPM, so we avoid having these blobs around.

Roger! I'll probably test this branch a little more before merging. If you have time please test on linux. Thanks.

If anyone could please test on linux before I merge...
