Move image/texture/sprite loading into Entity class

[jstamant]

I've been meaning to move the whole image/texture/sprite loading out of all the entities.

All the entities are individually loading+defining their own texture and sprite. It's not efficient, and isn't hard to optimize. Just let the Entity class deal with the common members like texture and sprite. The image, though, may have to be brought out to a different service class.

There was some work done towards this. It may have to be further improved.
