MOBSDK-302

- Added target for Mac OS X - AlfrescoSDK-OSX
- Renamed target for iOS - AlfrescoSDK-iOS
- Addition of AlfrescoOAuthNSLoginViewController
- Deprecated AlfrescoOAuthLoginViewController with AlfrescoOAuthUILoginViewController
- Added Mac OS X builds for CMIS following local patches for https://issues.apache.org/jira/browse/CMIS-831
- Fixed build scripts to include mac target builds of libraries and frameworks
    - scripts can now also be run with a space in the folder path


Potentially. I didn't see how this would be beneficial given that implementations would still have to be repeated in both implementation files. Also, keeping them separate would keep a more modular approach? Thoughts?
