Update README.md
Fix up format

Remove leftover portion of error message, where format string uses
an argument that no longer is passed, causing the error message to
have a random number added to it:

	Request failed: %@ (%d), got %d

The ", got %d" portion is a left-over from a previous iteration of
the message, and the value it expects is now the one provided in
the parentesis before it.
Change `AFHTTPRequestOperation` `-(id)initWithCoder:` to call the `super` implementation

This change allows an instance of AFHTTPRequestOperation to be more completely archived.
Update UIProgressView+AFNetworking.m

Hi there,
Thanks for the awesome job!!
Just found a tiny bug. I think in Line 174, the selector should be "countOfBytesReceived".
Cheers and have a nice weekend!!
