Merge pull request #475 from matzew/patch-1

fixed typo( resonse VS response)
Calling downloadProgress no longer casting [data length] to (long long)

AFURLConnectionOperationProgressBlock specifies "bytes" as an NSInteger. Master was casting [data length] as a long long, resulting in compilation errors if attempting to compile with more strict complication rules.

Only the totalBytes and totalBytesExpected are specified as (and correctly called with) long long values.
