feat(android): animate elevation

[m1ga]

JIRA: https://jira.appcelerator.org/browse/AC-6531

Being able to animate the elevation value.
Also removed some of the pre-Honeycomb stuff.

var win = Ti.UI.createWindow({
	layout: "vertical",
	backgroundColor: "#fff"
});

var v = Ti.UI.createView({
	elevation: 20,
	width: 200,
	height: 200,
	top: 50,
	backgroundColor:"#fff"
});
var v2 = Ti.UI.createView({
	width: 200,
	height: 200,
	top: 50,
	backgroundColor:"#fff"
});

win.add([v,v2]);

setTimeout(function(){
	v.animate({
		duration: 2000,
		elevation: 0,
		autoreverse:true,
		repeat: 10
	});
	v2.animate({
		duration: 2000,
		elevation: 20,
		autoreverse:true,
		repeat: 10
	});
}, 1000)

win.open();
