Updated the year in the LICENSE file.
Updated iOS example project to iOS 7.
Removed unneeded keys from Info.plist.
Updated static library project build settings to latest Apple recommdations.
Switched to @import for all Apple frameworks.

This fixes some sort of bug where #import <UIKit/UIKit.h> was causing
unambiguous symbol resolution.
First phase of rewriting FDRequestClient to use NSURLSession instead of NSURLConnection.

This is a rough first pass of the conversion to using NSURLSession.
There are many unnecessary files that can still be removed as well as a
bunch of NSURLSession edge cases that need to be handled but for simple
queries FDRequestClient now works with NSURLSession.
