Minor import paths issue

[soundspectrum]

Hello,

In AFHTTPRequestSerializer+OAuth2.h and AFOAuth2Manager.h, I suggest you change

#import <AFNetworking/...h>

to:

#import <AFNetworking.h>

for increased compatibility. They currently result in an error if include paths aren't set to include system paths, which is important to many developers.

Thanks,
Drew

Actually it should stay as #import <AFNetworking/AFNetworking.h>, otherwise it will break when used with cocoapods and the use_frameworks! flag.

I did note that the 3.0.0 branch switched to module imports (@import). Could this be reverted? Modules are not available when using objective-c++.
