added Window::Format option that enables native fullscreen button on mac
Fixing Mac fullscreen bug
Added startTime( float ) option to Tween::Options.

I often found myself working around not having this built-in, so
decided to simply add it. Very useful when queueing a series of tweens
in one go that you don't have strictly starting/stopping one after
the other.

resolve compile failure on bad C++ standard library value

perhaps the compiler default isn't valid when building on Xcode 4.6 or it needs to be set explicitly.

resolve OS X compile failure on bad C++ standard library value
Added bool Timeline::empty() method.

Mirrors std::container empty methods and is a useful counterpart
to the existing getNumItems(). Makes it easy to wait for animations
to complete before processing certain actions:
// e.g. in an update loop, don't process things if animating:
if( mSpecialTimeline.empty() )
{
 processSpecialItems();
}
