Feature request - events handling with more informations

Hi,
I want to use jsoneditor in a large project, but to do so I need to interact more deeply with the editor. To do so I need to handle events like : click, double click, right click, etc.
I patched the latest editor release but I'm unsure how to submit my modifications si here is a proposition :
Line 2753 add :

``` javascript
case 'contextmenu':
if(this.editor.options.contextmenu) this.editor.options.contextmenu(event,target,dom,node);
break;
```

Line 2735 add :

``` javascript
case 'dblclick':
if(this.editor.options.dblclick) this.editor.options.dblclick(event,target,dom,node);
break;
case 'click':
if(this.editor.options.click) this.editor.options.click(event,target,dom,node);
break;
```

Line 2711 add :

``` javascript
case 'contextmenu':
if(this.editor.options.contextmenu) this.editor.options.contextmenu(event,target,dom,node);
break;

```

Line 2693 add :

``` javascript
case 'dblclick':
if(this.editor.options.dblclick) this.editor.options.dblclick(event,target,dom,node);
break;
```

Line 2662 add :

``` javascript
// Modif YB
if(type == 'click' && this.editor.options.click) this.editor.options.click(event,target,dom,node);

```

Line 524 add :

``` javascript
// Modif YB oncontextmenu
this.frame.oncontextmenu = function (event) {
onEvent(event);
jsoneditor.util.preventDefault(event);
return false;
};
// Modif YB ajout du dblclick
this.frame.ondblclick = function (event) {
onEvent(event);

// prevent default submit action when JSONEditor is located inside a form
jsoneditor.util.preventDefault(event);
};
```

This allows me basically to fully handle events, including interacting with the clicked elements etc.
