FlexiGrid支持shift多选

在前面几章Flexigrid处理的基础上，处理了支持shift多选的功能，增加的代码标注了“//处理shfit多选 add by danielinbiti”

主要增加了三部分代码

第一部分

(function ($) {
	$.addFlex = function (t,p) {
		if (t.grid) return false; //return if already exist
		p = $.extend({ //apply default properties
			height: 200,//default height
			width: 'auto',//auto width
			striped: true,//apply odd even stripes
			novstripe: false,minwidth: 30,//min width of columns
			minheight: 80,//min height of columns
			resizable: true,//allow table resizing
			url: false,//URL if using data from AJAX
			dwrAction:function(){},method: 'POST',//data sending method
			dataType: 'xml',//type of data for AJAX,either xml or json
			errormsg: 'Connection Error',usepager: false,nowrap: true,page: 1,//current page
			total: 1,//total pages
			useRp: true,//use the results per page select box
			rp: 15,//results per page
			rpOptions: [10,15,20,30,50],//allowed per-page values 
			title: false,pagestat: 'Displaying {from} to {to} of {total} items',pagetext: 'Page',outof: 'of',findtext: 'Find',procmsg: 'Processing,please wait ...',query: '',qtype: '',isColSel:true,nomsg: 'No items',minColToggle: 1,//minimum allowed column to be hidden

			onSubmit: false //using a custom populate function
		},p);
		$(t).show() //show if hidden
			.attr({
				cellPadding: 0,cellSpacing: 0,border: 0
			}) //remove padding and spacing
			.removeAttr('width'); //remove width properties
		//create grid class

			}
