Title: Change behavior to addSecond to SideLayout to make the result more intutive

So before, when you made:
```java
buttons = new LeftRightLayout();
buttons.addRight(new Button("OK"));
buttons.addRight(new Button("Cancel"));
```
Visualization of buttons where
```
Cancel | OK
```
When this change they are shown like:
```
OK | Cancel
```
