reformat source with esformatter

yeah, getting really "meta".

still unsure if these should be the used settings or not.. specially since our default settings are not exactly what I would like them to be - I don't like spaces before `?`, have a mixed feeling about spaces inside `()`, and like `else if` to be on it's own line... also unsure if indent should use 2 spaces instead of 4.

closes #85
see #77
