New app: Dutch clock

[whenlit]

A clock that tells the time the way a Dutch person might answer you if you asked them what time it is. It is configurable in a number of ways.

This is my first contribution here, please do not hesitate to tell me if I'm doing anything wrong.

I guess 1 version in ChangeLog would be enough for now.

More importantly, we have approxclock already. Should we start somehow merging them before we have czech-clock, french-clock, polish-clock ... etc?

Hi @pavelmachek, thanks for taking the time to look at this. You're right, the origin story of this particular app may not be interesting to everyone. I pruned the Changelog a bit.

Regarding approxclock et al: I'd be happy to help with some kind of abstraction of approximate clocks (a library? a word-based clock with internationalized rules?) but the main point of this particular clock is not so much about approximateness but more about the idiosyncrasies of the Dutch way of telling time ("it's slightly past ten before half six" (5:21) and such).

Hi! The changelog looks good. If it can't be easily merged, I guess we don't merge, sorry for the noise.

Thanks for the app and the swift communication! Always nice to see new contributors! :)
