End times and prettier files

Changelog:

• End times are now also parsed, additional to the start times.
• Original time strings are now ommited since they are already very reliable to parse.
• JSON files are now human-readable.

To me, it's still unclear which timezone is used for the dates. On my Raspberry, these are local times (the behavior I expect), but on my PC they are -1 hour (which currently is UTC). If someone has an idea how to handle this properly, let me know.

It's alive

It may be pretty useless, but for those who don't want to mess with node.js (which is a shame because it's great), I give you some binaries as well. Can't guarantee that they work as reliably as they should, but in theory they should...

Made with "pkg", no extra arguments, no config.

Have fun
