Fix hyperlinks to references

Fixes #107

(and minor adaptions to build.sh and wording at lni.dtx)

I am not sure, whether loading in the middle of the preamble is a good idea. We should look for another solution IMHO.

We should keep the load order, but work with hyperref=manual and \BiblatexManualHyperrefOn. See https://github.com/gi-ev/LNI/tree/fix-107-ms

The fix looks nice! Thank you.

In general, we should think about supporting addition of packages, which need to be loaded after hyperref. A huge discussion is at https://tex.stackexchange.com/q/1863/9075. - I am very glad that no user reported issues in loading additional packages. I am unsure whether this is luck or because the class is properly engineered ^^.

Maybe using pkgloader could help? However, this is a solution not widely in use and may cause other issues.

I close this PR and will merge the other commit to move forward.
