Create nginx redirect configuration script for accepted ProtoXEPs

[tfar]

When a contribution comes in, the ProtoXEP is placed in the /inbox folder, and people discuss it. In case it's accepted as experimental XEP, the ProtoXEP is moved to the xeps root / folder. It would be nice if the old files would redirect to the new one.

It should be possible to write a short bash or python script that does the right git query and creates a config snippet full of nginx redirect rules for the inbox XEPs to their xep-####.xml/html equivalent.

On the server we could then run that script and include the output of the script in our nginx config.
