Title: [fix #124] Make default API prefix relative

When using \BlueLaTeX from behind a proxy, if the API prefix is
absolute, then it might lead to some problems because the client send
the request to `/api`.
This is a problem iF \BlueLaTeX is not accessed at the root before
the proxy rewrites the URL.
