New strings in gnome-games

[Adrien Plazas <kekun plazas laposte net>]

Hi,

A new feature[1] has been added to gnome-games after the break: a new preferences page has been added, introducing a few new string.

Hopefully these should be the last user facing string changes for this cycle of gnome-games.

Cheers,

Adrien Plazas
