Overrides for opencl-comptible rocks
The idea is to add this to the luarocks source servers path ahead of the main torch rocks repo, ie something like:
rocks_servers = {
[[https://raw.githubusercontent.com/hughperkins/rocks-cl/master]],
[[https://raw.githubusercontent.com/torch/rocks/master]],
[[https://raw.githubusercontent.com/rocks-moonscript-org/moonrocks-mirror/master]]
}
It will only override where needed, and otherwise fall through to standard torch rocks server.
