{new engine benchmarks} Current game engine benchmarks

I have completed the 1^st phase of the engine re-write and have calculated some benchmarks for those part of the system that are currently working. As soon as the collision engine is up and running I will be able to post the other benchmarks.

*These numbers are dodgy as visual inspection would suggest that the old engine is only drawing a frame every couple of seconds. Also all the sprites are sat on top of each causing over 1, 500, 000 collision checks are performed for each frame.

You can't really expect every game object to interact with every other game object.

The data shows that in terms of drawing and updating speed the new engine is very fast compared to the old one, but text drawing (which happens a lot with bin displays) is still slow. I'll investigate this at a later date.

A few more tests and checks and I'll publish the game engine and a game start template.
