Status:
It works well, but there are still a few details to improve/fix
More details about the changes:
- New dependency on Arabica and Libxml2 to parse the XML
- Loading the old format is still supported for this release, but won't be supported anymore in the next one
- Games are now only saved in the new format
- In training mode, the player is now created externally, like in the other modes
- Avoid using GameIO (the one from game/) whenever possible
- Do not use a FILE* argument anymore when loading a game
- Throw and catch exceptions correctly when a game cannot be loaded or saved
- The non-regression tests now use a new method to print the game history
