player lean, player models lean in the direction of movement (use g_playerLean to scale or disable the effect (client side))

horizontal speed fully maintained when crouch sliding and hitting a ramp (previous version had a little dip)
si_fps limited to 90fps for q4mp/, now declared in gamecode so mods can change their max
