Internally, commands are now stored a bit differently: some commands which were at the end of a turn (like the players rack in duplicate mode) are now at the beginning. But from a user point of view, there is no visible difference, except some details in training mode (and the new behaviour is arguably better :)). Only (known) problem: after loading a game saved before this commit, navigating in the game history may be less nice (in particular, racks may not be fully restored).

/**

* Handle the navigation in the game history.

*
|
|
* A few assumptions are made for the design:
|
|
* - each turn in the game is represented by a TurnCmd object
|
|
* - the current TurnCmd object is always in the "partially executed" state
|
|
* (see class documentation), except maybe for the last turn
|
|
* - previous turns are fully executed, and future turns are never executed
|
|
* - addind a command can only be done if the current turn is the last one
|
|
* and is fully executed
|
|
*
|
|
* Many assertions are there to help enforce this design.
