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

Patch Chromium bug

Don't use includes to make IE happy and avoid Polyfill

use date.toLocaleDateString to format year/month

refactor and reduce code logic

Return empty string if the date input doesn't parse

remove Array.find to make IE11 happy

Add week start (locale setting)

Refactor cell click handler and add more date picker and date range picker tests

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

Broken initial scroll in time-picker with steps

Date utility functions `prevMonth` and `nextMonth` change the source
date when using `src.set[Date|Month|FullYear]()`. This change creates a
copy of the date at entrance of function so we have a pure function.

Made some code refactor and added specs for these functions.
