Subject: [PATCH] WIP: add an input_datetime (#418)

* Initial work on input_datetime

* Properly format date and time

* Linting

* Use dom-if

* Converting to Polymer 2 class

* Some linting

* Cache domain, linting

* More linting

* Use on-value-changed instead of value observer.

Also, fix off-by-one b/c of 0-indexed months. Thanks, JavaScript.
