Update _jsbeautify from version 2.2 to 2.3

improved the format of the result:
Example:
in version 2.2
<code>	var a = [[[{
		a: 'a'
	}, {
		A: 'A'
	}], {
		b: 'b'
		,B: 'B'
	}], [{
		c: 'c'
	}, {
		C: 'C'
	}], {
		d: 'd'
	}, {
		D: 'D'
	}]
</code>
in this version 2.3:
<code>
		var a = [[[{
						a: 'a'
					}, {
						A: 'A'
				}], {
					b: 'b'
					,B: 'B'
			}], [{
					c: 'c'
				}, {
					C: 'C'
			}], {
				d: 'd'
			}, {
				D: 'D'
		}]

</code>
it's good for fold method in VIM when fold method's value is "indent"
