Major progress with version 2.0.0.
Change OperatingSystemInterface
Move the OSInterface to a separate module
Separate a OSInterface from LibInterface
remove all references to android.Context and android.Activity from distorted-objectlib
Move the control of object scaling out the objectlib.Thee xact way the object is scaled needs to be decided in the app, as only the app knows that e.g. in the Rubik main screen, if it is a square, then obejct needs to be a bit smaller than in case of Config screen (if that one happens to be a square)
config: license.
Fix setDefaultRotation() when changing an object; do it at exactly the right time when the 'old' object has already disappeared, but the new hasn't been attached to the Nodee yet.
Progress with ConfigScreen.
Beginnings of the ConfigActivity.
