Fix T37898: blenderplayer painfully slow in recent builds

Issue was caused by recent image cache rewrite and root of
the issue goes to the fact that blender player doesn't
initialize cache limiter and it uses 32meg of memory only.

This leads to infinite image loading/freeing.

For now disabled cache limiter in game engine, this brings
back old behavior.

In theory we might be smarter here, but better caching
policy is to be discussed.
