Olivier Teulière 7569a58bb7 Each letter (tile) now has a display string, defaulting to its internal char. It is not yet possible to change it.
This display string is used in the ncurses and Qt interfaces.

Display strings are types "wdstring" instead of plain "wstring" in a few places (not all of them) to help recognize them.
