Merge pull request #49 from pokelabo/feature/cocoapods

FIX: typo
New project structure.

ObjectAL is now structured as projects within a workspace:

 * ObjectAL: Contains library targets for iOS and Mac, and the documentation builder.
 * ObjectALDemo: Contains targets for the iOS and Mac demo apps.

The cocos2d library used by the demo app should no longer pollute Xcode's inspector when you include ObjectAL as a subproject or as part of another workspace.
Fix for memory leak when slicing, and fix for compiler warning.

Also, the podspec was pointing to the wrong tag.
