Update MFSideMenuContainerViewController.m

[craigisakson]

Added code to account for notification bar side as well as a bug I encountered when apps were opened in landscape, you could not view the entire menu due to the frame not being correct if the view that contained the slide-out menu was not the initial view.

I also encountered his bug. Side menu hight is to big, when starting in portrait and rotating to landscape and then open the side menu. Views positioned at the bottom of a side menu are not visible in this case. Please merge this bug.
