Add blocks-based method to UAGithubURLConnection.

+ (void)asyncRequest:(NSURLRequest *)request requestType:(UAGithubRequestType)reqType responseType:(UAGithubResponseType)respTyp success:(void(^)(NSData *, NSURLResponse *))successBlock_ failure:(void(^)(NSData *, NSError *))failureBlock_;

Takes a successBlock and a failureBlock, removing the need for delegate callbacks etc. Influenced by https://github.com/rickerbh/NSURLConnection-Blocks.
