升级上周的js模版引擎 支持include

(function(window , undefined){
    var cache = {};
    var etic = window.etic = function (str, data){
        str = str.trim()
        if (!cache[str] ){

　　　　　　　　var tpl = document.getElementById(str)
　　　　　　　　if (!tpl) throw 'tpl:' + str + ' is not load'
　　　　　　　　tpl = tpl.innerHTML

　　　　　　　var fCon = 'var p = [];function __require(id){ \
                    return function(data){ return etic(id).apply(data,arguments);} \
                };function __append(h){return p.push(h)}'

            while (true){
                var pst = tpl.indexOf('<?')
                if (pst < 0) {
                    fCon += "p.push('"+ tpl.replace(/[\r\t\n]/g, " ") +"');return p.join('');"
                    break
                    }
                    var pend = tpl.indexOf('?>' ,pst)
                    var preHtml = tpl.substr(0,pst)
                                    .replace(/[\r\t\n]/g, " ")

还未支持异步加载....总感觉异步加载模版的话会变慢 - -!  模版的依赖应该在服务端拼装的时候能解决掉
