Subject: [REF] web: add module system to the web client

This commit introduces a new module system for the javascript code.
Instead of using global (namespaced) variables everywhere (like
openerp.web.whatever, ...), each file declare one (or more) module
with its dependencies.  Each module will be loaded after its
dependencies, and will be given a reference to the return values.

This change is a massive departure from the way the client worked
previously.  It will sadly break some/most history, but I am sure that
the future git ecosystem will allow you to easily browse the history
past this revision (one can dream).

This commit feature:
* main namespace is now odoo instead of openerp
* a way to define modules and dependencies (inspired by requirejs)
* many files have been splitted in simpler subfiles
* basic support for debugging in odoo.__DEBUG__
* no global variable (i.e. nothing in window.openerp)
* many bug fixes, many new bugs

Future vision: this modularization should simplify future code
development, simplify debugging and will allow a serious testing effort

+ *
+ * Adds "include()"
+ *
+ * Defines The Class object. That object can be used to define and inherit classes using

+ *   dance: function(){

+ * });
+ *
+ * The init() method act as a constructor. This class can be instancied this way:
+ *
+ * var person = new Person(true);
+ * person.dance();
+ *
+ * The Person class can also be extended again:
+ *
+ * var Ninja = Person.extend({
+ *   init: function(){
+ *     this._super( false );
+ *   },
+ *   dance: function(){
+ *     // Call the inherited version of dance()
+ *     return this._super();
+ *   },
+ *   swingSword: function(){
+ *     return true;
+ *   }
+ * });
+ *
+ * When extending a class, each re-defined method can use this._super() to call the previous
+ * implementation of that method.

+/**
+ * Base class for all visual components. Provides a lot of functionalities helpful
+ * for the management of a part of the DOM.
+ *
+ * Widget handles:
+ * - Rendering with QWeb.
+ * - Life-cycle management and parenting (when a parent is destroyed, all its children are
+ *     destroyed too).
+ * - Insertion in DOM.
+ *
+ * Guide to create implementations of the Widget class:
+ * ==============================================
+ *
+ * Here is a sample child class:
+ *
+ * MyWidget = openerp.base.Widget.extend({
+ *     // the name of the QWeb template to use for rendering
+ *     template: "MyQWebTemplate",
+ *
+ *     init: function(parent) {
+ *         this._super(parent);
+ *         // stuff that you want to init before the rendering
+ *     },
+ *     start: function() {
+ *         // stuff you want to make after the rendering, `this.$el` holds a correct value
+ *         this.$el.find(".my_button").click(/* an example of event binding * /);
+ *
+ *         // if you have some asynchronous operations, it's a good idea to return
+ *         // a promise in start()
+ *         var promise = this.rpc(...);
+ *         return promise;
+ *     }
+ * });
+ *
+ * Now this class can simply be used with the following syntax:
+ *
+ * var my_widget = new MyWidget(this);
+ * my_widget.appendTo($(".some-div"));
+ *
+ * With these two lines, the MyWidget instance was inited, rendered, it was inserted into the
+ * DOM inside the ".some-div" div and its events were binded.
+ *
+ * And of course, when you don't need that widget anymore, just do:
+ *
+ * my_widget.destroy();
+ *
+ * That will kill the widget in a clean way and erase its content from the dom.
+ */
