Cast manager now caches based on memory usage of the cached action frame

images, except that this is all fucked because the action frames get
generated on the fly which means that we'd need to update the LRU cache
with info on our new size which would hugely complicated things, so
instead we're going to rework the whole business in the future to cache
individually composited images rather than the whole goddamned action
frame kit and kaboodle.
