Freeze gameobject M2 animations to prevent cycling

Browse source 
Gameobject M2 instances (books, crates, chests) were continuously
cycling their animations because M2Renderer unconditionally loops
all sequences. Added setInstanceAnimationFrozen() and freeze all
gameobject instances at creation time so they stay in their bind pose.
