Fix links

[nsoranzo]

that reference a renamed master branch.

Also:

• Remove some more master references
• Update "standards" git submodule

Thank you @nsoranzo!

[nsoranzo]

Speaking of master branch, any chance we change the default branch for this repo #1342 ?

[mvdbeek]

Yes, I think we should!

[nsoranzo]

I'd do it, but I don't have admin rights on this repo :)
Unless you'd like to have also @jmchilton's approval?

[mvdbeek]

I can rename the repo default branch, but there's a lot of link updating to do, no ?

[nsoranzo]

I think most of the stuff should continue to work as GitHub automatic redirects links, but there's only one way to know :D
One think that we would need to update (but I also don't have access to) is https://readthedocs.org/projects/planemo/

First thing after GCC is done ? 😆
