Add a Benchmark to Minecraft

Since Minecraft is so popular, one of the primary things people think about when they buy a new computer is will it run Minecraft? If so how well? Currently, there is really no answer to this question as there is no universal standard. Therefore there needs to be a way to benchmark in Minecraft so we can know what parts to buy in order to get the framerates we desire. So I would suggest that a "Run Benchmark" button be added into the Options menu, that would run a quick benchmark in a test world. This way we could have a standard for how well a computer can run Minecraft.
