OS X support (without CUDA)

The framerate will probably be very slow without CUDA, but I think otherwise it should run anyway.

I have one of the last Macs with an NVIDIA GPU (27" iMac from Late 2012) and while I have the latest CUDA drivers installed, torch doesn't see it.

>>> import torch
>>> torch.cuda.is_available()
False

Also, I see there are 34 places in the code that move tensors or models into the GPU, each of which would need to be modified to work without the GPU.

I fixed this in b700f46 so now it runs without GPU, but much more slowly.

For some reason, Ubuntu CPU-only is about 5x faster than OS X on fairly similar hardware.
