Support for iPhone X safe area

[calbot]

Bottom toolbar gets cut off on iPhone X so here's what I did to fix it.
Updated MWPhotoBrowser.m

- (CGRect)frameForToolbarAtOrientation:(UIInterfaceOrientation)orientation {
    CGFloat height = 44;
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone &&
        UIInterfaceOrientationIsLandscape(orientation)) height = 32;
    CGFloat adjust = 0;
    if (@available(iOS 11.0, *)) {
        //Account for possible notch
        UIEdgeInsets safeArea = [[UIApplication sharedApplication] keyWindow].safeAreaInsets;
        adjust = safeArea.bottom;
    }
	return CGRectIntegral(CGRectMake(0, self.view.bounds.size.height - height - adjust, self.view.bounds.size.width, height));
}

如果不好使，另加一个其它方法

这一块代码，在commit 66ddd73-on Apr 22, 2016基础上添加的，使用工程中的Library photos and videos一块，UI在iPhoneX上我这边试了下是OK了，其它建议类推。希望能帮到你。
