Make jquip aware of CommonJS/AMD

[IngwiePhoenix]

I just threw jquip into my system instead of jQuery...and straight away saw a problem:

    ;$['plug']("ajax", function ($) {

This line throws an "$.plug is not defined" error. The entire code is wrapped in these lines:

/* 2 */
/***/ function(module, exports, __webpack_require__) {
    /* WEBPACK VAR INJECTION */(function($) {

    // ... snip. Jquip goes in here.

    /* WEBPACK VAR INJECTION */}.call(exports, __webpack_require__(2)))
/***/ },

The __webpack_require__(2) resolves to that very module. This can, but does not have to, happen. A solution would be to replace first or second line of jquip with this:

// Original
    window['$'] = window['jquip'] = (function(){

// Replace
    var $ = window['$'] = window['jquip'] = (function(){

This way, we gain these things:

• A local reference to the object that we are building. Previously polluted $'s will be shaddowed by this one.
• We can figure out if we have module.exports present and return jquip this way, too.

At the start or end of jquip:

if(typeof module != "undefined" && typeof exports != "undefined") {
    // "return" the jquip instance.
    exports = $;
}

I am not very familiar with AMD, but the first 20 lines of jQuery show a good example on how to go about them.

For now I have to fall back to jQuery, since there is no appearant way I can monkeypatch this problem out without having to fork this project ... for one line, at most.
