Changed order of title assignment in example view controllers `-[viewDidLoad]`.

This way the title is correct when we go into the view did load stage, and it's easier to get the correct title if we are using the REMenu from a title view/button.
Added a `maxImageSize` property to `REMenuItemView`

This way if much larger images are passed in, they won't run over into other menu items unless wanted.
Added tintColor support for images with template rendering mode.
