Add links to JADE and CUDA material

On your webpage:

http://www.hpc-uk.ac.uk/facilities/

Can you please make the JADE link point to

http://www.jade.ac.uk/

Also, under training, perhaps you could add a link to my CUDA course:

http://people.maths.ox.ac.uk/~gilesm/cuda/

and the UK HPC Autumn Academy:

https://www.csc.cam.ac.uk/events/HPC

which I think is still running.

Updated link for JADE and added link to CUDA course. Need to query if Autumn Academy is still live.
