Respect the accessibility setting "Bold Text" on iOS7, when implementing Dynamic Type with a custom font.

	BOOL MTDIsBoldTextEnabled(void) {
	static BOOL boldTextEnabled = NO;

	static dispatch_once_t onceToken;
	dispatch_once(&onceToken, ^{
	// Hack that checks if the "bold text" flag in the accessibility settings is enabled
	UIFont *font = [UIFont preferredFontForTextStyle:UIFontTextStyleBody];
	boldTextEnabled = [font.fontName rangeOfString:@"MediumP4"].location != NSNotFound;
	});

Delegate proxying (`protocol_methodForEach()` is a custom function that does just what its name implies)

	@interface DDDelegateProxy : NSProxy

	+ (id)proxyForDelegate:(id)delegate conformingToProtocol:(Protocol *)protocol;

	@property (weak, readonly) id delegate;
	@property (strong, readonly) Protocol *protocol;

	/*!
	* Set a default return value for a method on the delegate's protocol.
	* \param value This must be a block that returns the default value. Bad Things will happen if it's not.

Workaround to vanilla UICollectionView+UICollectionViewFlowLayout using non-integral origins, leading to blurry cells.

	@implementation BHSCollectionViewFlowLayout

	- (NSArray *)layoutAttributesForElementsInRect:(CGRect)rect {
	NSArray *allAttrs = [super layoutAttributesForElementsInRect:rect];
	for (UICollectionViewLayoutAttributes *attributes in allAttrs) {
	attributes.frame = CGRectIntegral(attributes.frame);
	}
	return allAttrs;
