Bugfixes for touch control - specifically for furious swiping and concurrect backing of moves.
Block the object, menu & back moves while we're scrambling!
Some improvements to blocking, mostly to the names of variables.
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!

Bandaged 3x3: remember object state and move history.
Remember move history in the PLAY and SOLV screens.
Add info pane: part 1.
Convert the theme to be a MaterialTheme and the TransparentImageButton to be a MaterialButton - the first forced by the second, and the second because a MaterialButton gives us control over the location of the icon in top of it. We need that because of the new 'solve/scramble' split-button in the lower right of the Play screen.
Further simplifications.
Remove the concept of a 'TwistyActivity' altogether.
