Two childControllerContainerView's are initialized

[kcharwood]

The -childControllerContainerView initializes two instances of _childControllerContainerView, both are added to the MMDrawerController's view. The issue occurs because the first initialization requests self.view.bounds. At that time self.view is nil so the view gets loaded, and viewDidLoad gets called. The viewDidLoad method sets the childControllerContainerView's background color which leads to a second initialization of childControllerContainerView because at that time the view is still nil:

This can be fixed by modifying the -childControllerContainerView method to look like this:

-(UIView*)childControllerContainerView{
    if (_childControllerContainerView == nil) {
        CGRect b = self.view.bounds;
        if(_childControllerContainerView == nil) {
            _childControllerContainerView = [[UIView alloc] initWithFrame:b];
            [_childControllerContainerView setBackgroundColor:[UIColor clearColor]];
            [_childControllerContainerView setAutoresizingMask:UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth];
            [self.view addSubview:_childControllerContainerView];
        }
    }
    return _childControllerContainerView;
}

Fixed in #153.

@JonasGessner Thanks for pointing this out. I pulled into a new PR to separate the other issues you reported in #153.

This PR should fix this one.

Thanks again!
