Display a random tip during map loading or in main menus

Add the newly created https://wiki.unvanquished.net/wiki/General_tips link, plus the probable tips for classes and/or equipments.
I also think that "tip of the day" could be displayed in other places than map loading, like the "main menu" (in which one would be able to browse them, maybe disable some) or when waiting for respawn.
Ideally, those tips would be translated, but their simple existence would be a really good start, still. Unvanquished is a game with lot of undocumented tricks, which helps knowing players humiliate newcommers (even without wanting it) and thus probably does not help newcomers to stay around.
