Review: not-recorded

- it's improved clone of `j-Calendar`
- supports __dark mode__
- supports __touch gestures (swipe)__ and fixed full size on mobile

__Configuration__:

- `firstday {Number}` first day in the week (default: `DEF.firstdayofweek`)
- `today {String}` a label for the `Set today` button
- `clear {String}` a label for the `Clear` button
- `days {String}` days e.g. `SU,MO,TU,WE,TH,FR,SA` (default).
- `months {String}` months e.g. `January,February,...` (default).

The component must be called manually or works with `j-Input` component automatically. The component is a singleton.

- __important__ add the calendar component under `<body>` element

## Usage

```javascript
var opt = {};
opt.element = YOUR_ELEMENT;
opt.value = new Date();
// or opt.value = 'path.to.date'; --> then "opt.callback" is disabled
// opt.align {String}      : align "left" (default), "center" or "right"
// opt.position {String}   : position "top" (default) or "bottom"
// NEW: opt.clock {Boolean} : enables time (default: false)
// NEW: opt.ampm {Boolean} : enables AM/PM (default: false)

opt.clear = false; // Removes "clear" button from datepicker. If this property is not specified as "false" - "clear" button will be shown

opt.callback = function(newdate) {
	console.log('date has been changed');
};
// IMPORTANT - opt.callback() can receive "null" value as a parameter, so this check should be taken into consideration when callback function is being created.

// opt.offsetX {Number} "x" offset
// opt.offsetY {Number} "y" offset
// opt.close {Function} optional, this function can determine closing of DatePicker

// NEW and OPTIONAL
// It's callend when the DatePicker changes year/month
opt.badges = function(date, append) {
	// Appends small and red badges to the current view/month
	append([date1, date2, date3]);
};

SETTER('datepicker/show', opt);
```

Use it with `<ui-component name="datepicker">`. When the component is not loaded yet, jComponent downloads it on first use from the address in `DEF.fallback` (the Componentator CDN by default). Author: Peter Širka. Source: the Componentator components repository, MIT license.

<a href="#datepicker">SHOW DATEPICKER: <b><ui-bind path="form.date" config="html:value?value.format('dd.MM.yyyy'):DEF.empty"></ui-bind></b></a>
<ui-component name="datepicker" config="today:Set today;firstday:0"></ui-component>

	var form = {};
	form.date = new Date();

	$('a[href="#datepicker"]').on('click', function(e) {
		var opt = {};
		opt.value = 'form.date';
		opt.element = this;

		// Append badges
		opt.badges = function(date, append) {
			setTimeout(function() {
				append([date.add('-5 days'), date.add('-2 days'), date.add('3 days'), date.add('8 days')])
			}, 1000);
