Remove local fomatto

Well fomatto is in npm, but unfortunately it's only `0.5` which doesn't play nice with browserify (the reason I started digging around in this).  As of version `0.6` it does, but that hasn't yet been published - I've raised BonsaiDen/Fomatto#6 though hopefully it will be soon.

Waiting until it has been published and then updating package.json to use `0.6.0` is probably a better idea than using the github repo...
