* Introduces RKRequestCache for cacheing responses (supports ETag conditional GET, use cache if available, use cache on error, etc.) closes #75 * Updates to Three20 layer to eliminate need for intermediary TTTableItem classes closes #76 * Fixes to ensure iOS 3.x compatability: * Switched compiler to Clang * Updated conditional checks for UIBackgroundTask symbols to ensure runtime safety on iOS 3.x * Removed unnecessary linkage against UIKit and CoreFoundation from library targets * Fix for issue where RKRequest objects could become stuck in infinite loop within RKRequestQueue loadNextInQueue if you start a request and then cancel immediately. On cancel only decrement loadCount if the request has start loading. refs #122
