Fix crashes that could occur when keeping two fonts loaded concurrently.
Since 2002-09-03, SDL_ttf performs reference counting on TTF_Init and TTF_Quit. If two fonts were loaded concurrently via the Font class and one was destructed, the destructor of the first object would call TTF_Quit, making the second object unusable. The constructor now calls TTF_Init unconditionally to prevent this situation. The reference counting behavior was introduced in this SDL_ttf commit: http://hg.libsdl.org/SDL_ttf/rev/fc0371908009
