map.addControl support multiple controls

these simple patch allows you to add an array of controls(like as map.addLayer) in a single line of code. 
It 'a very useful when working on big webmapping applications with many controls!

*current solution:*
```
map.addControl(panels.profile);
map.addControl(panels.friends);
map.addControl(panels.place);
map.addControl(panels.user);
map.addControl(controls.search);
map.addControl(controls.gps);
map.addControl(controls.zoom);
map.addControl(controls.attrib);
map.addControl(controls.alerts);
map.addControl(buttons.status);
map.addControl(buttons.profile);
map.addControl(buttons.friend);
```
*3dparty solution(underscorejs):*
```
_.invoke([
	panels.profile,
	panels.friends,
	panels.place,				
	panels.user,
	controls.search,
	controls.gps,
	controls.zoom,				
	controls.attrib,
	controls.alerts,	
	buttons.status,
	buttons.profile,
	buttons.friends
],'addTo', map);
```
**patch solution:**
```
map.addControl([
	panels.profile, panels.friends, panels.place, panels.user,
	controls.search, controls.gps, controls.zoom, controls.attrib, controls.alerts,
	buttons.status, buttons.profile, buttons.friends
]);
```
