Enable text selection in Internet Explorer

Currently (Unlike all other browsers) there is no way to select text in draggable objects in internet explorer even if a handle is provided.

This is caused by two pieces of code.

Firstly: (This code should be removed)

in $.ui.mouse -> mouseInit
// Prevent text selection in IE
if ($.browser.msie) {
	this._mouseUnselectable = this.element.attr('unselectable');
	this.element.attr('unselectable', 'on');
}

Secondly: (These functions require the last line of code to be added)

in $.fn.extend

enableSelection: function() {
	return this
		.attr('unselectable', 'off')	//Not sure if needed now
		.css('MozUserSelect', '')
		.unbind('selectstart.ui');
		.unbind('selectstart.disableTextSelect');	//ie select enable
},

disableSelection: function() {
	return this
		.attr('unselectable', 'on')	//Not sure if needed now
		.css('MozUserSelect', 'none')
		.bind('selectstart.ui', function() { return false; })
		.bind('selectstart.disableTextSelect', function() { return false; }); //ie select disable
},

What do people think?

Works for me.
