Tool improvements

[akx]

• don't invoke wget separately for each file
• note that Cython is required for a successful install
• pin the external download versions (submodules would be better still really)

Hello,
Sorry for the late reaction.
What would be the real advantage of calling wget with a list of arguments instead of a for loop on a list ? Is it slow for you ?
I feel that a list of tools which will be installed is more flexible and one can more directly see what is needed

As I mentioned in the commit message, wget can then reuse the same connection for all files and not do TCP dances and HTTPS negotiation again and again. It's plenty faster than the original.

I'm not following what you mean here. There's no changes to the lists of files downloaded.
