UR.IMG.UR non-trivial Nibitaph RESTful macOS/iOS sample now buildable

After a little Saturday morning maintenance, the UR.IMG.UR github repo should be now easily build-able with Xcode 4.6 (macOS) and Xcode 5.1 (iOS 8.x-).

Tidied up the Xcode projects, added some missing resources, updated the Xcode folder references to use the Nibitaph submodules.

UR.IMG.UR non-trivial Mac/iPad single source sample code

Just did an initial push of the UR.IMG.UR sources as submitted to the Mac and iOS app stores. The code makes full use of the Nibitaph 'framework' code, realizing a high degree of code sharing between the macOS and iOS builds.
