* 3) Skeletal models functionality:
* - add multianimation system: weapon animations (not a car / byke case: it ia two entities
* with the same coordinates / orientation);
* - add head, torso rotation for actor->look_at (additional and final multianimation);
* - add mesh replace system (I.E. Lara's head wit emotion / speek);
* - fix animation interpolation in animations switch case;
* 6) Menu (create own menu)
* - settings
* - map loading list
* - saves loading list
* 10) OpenGL
* - shaders
* - reflections
* - shadows
* - particles
* - GL and renderer optimisations
* 40) Physics / gameplay
* - optimize and fix character controller, bug fixes: permanent task
* - weapons
