Simplifies & refactors the way
git log fields are parsed
`--pretty=tformat` string is generated automatically from array of `git log` fields. Each field is separated by a null character, which as far as I know can't appear naturally in any of those fields. Babel now transpiles from .es to .js, which is easier than transpiling to .compiled.js now that there are multiple .es scripts
