Magic Cube

More fixes for UI in case of extreme screen (w/h) ratios ( from 1.0 to 2.0 ).

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)

Further improvements for the UI.

Improve UI proportions on squarish screens.

Progress with 'Stars' dialog.

Released 1.11.6 version

Make it possible to decide about FastScramble duration fromo outside the ObjectControl.

Make several objects built-in
oone fix for USE_IAP

Very important bugfix for an issue which probably has been the reason for many mysterious behaviours in the past: the JsonReader class cannot be a singleton! Convert it into a normal 'instanced' class.
With it being a singleton there's a major issue: when we create a new TwistyObject from a JSON file (by, for example, going to PurchaseActivity) and then we come back to the old object (by, for example, going back to the main RubikActivity) - then the JsonReader inside the old object has read the new JSON file and thus many of the 'abstract' methods in the old TwistyObject (for example getShortName()) all of the sudden start returning new values!

Purchase Pane: post-purchase dialogs.
