fixes #3277

refactor Datepicker  to render subcomponents in template instead of
creating new Vue instances

remove Array.find to make IE11 happy

Added `cell.date` so we don’t need `. getDateOfCell()` anymore
Passed `cell` directly in `@click="handleClick(cell)”` so we don’t need
`const cell =
this.cells[parseInt(event.target.getAttribute('index’))];` anymore

since now the index of the `[hours|minutes|seconds]List` might not
anymore match the correct number in value

This ads the possibility to choose `steps` in the formatting of the
lists. So we can have ”5 in five minutes” or ”every 15 minutes” instead
of having always lists of 60 items/minutes.
