But we don't need to sort them all the time, and in general we don't even need to keep all the rounds.
This commit greatly improves the search performance by filtering the results in 3 different ways, depending on the context:
- A limit to the number of results can be given (useful for the training mode). The kept results are the best ones, not the first ones found by the search.
- When only the best round is needed (when the AI is playing with level 100, or when preparing the rack for an explosive game), we don't need to keep rounds with a lower score
- When the AI has a level lower than 100, it is still possible to skip many rounds
The search limit in training mode is configurable (defaulting to 100) and can be deactivated.
- Allow displaying letter points on the board with an option (on by default)
- Fixed the tab order on the preferences window
- Improved the behaviour and default size of the preferences window
- New (optional) dependency on the libconfig library, to save/load configuration files.
- On Unix, the location of the configuration file respects the XDG Base Directory Specification.
- The contrib system automatically fetches and builds libconfig for Windows cross-compilation
- Fixed make distcheck
- Initialize the random numbers generator, and print the seed value
- Handle properly Qt builds without STL support
- Save the position of the main window
- Got rid of the useless toolbar
- Better size of the preferences dialog
- Hopefully fixed translation issues on Windows
- The Settings class throws an exception when asked for a non-existing setting
- Added auxiliary windows for the history and the external board
- Gave a title to auxiliary windows and remember their position (more or less) and size
- Auxiliary windows do not survive anymore after the main one
- Preferences are now stored in a sensible place
- Ensure unicity of players names (in the interface only, not the core)
- Update the main window title with the game type
- Display the player name in the history
- The history widget is now able not to align the rack and the corresponding word
- The dictionary path is remembered in the preferences
- Ask for confirmation when loading a dictionary in the middle of a game
- Preview tiles are coloured differently, and joker characters are in lowercase
