Fix weblink to Database_backends wiki page

[Desour]

clickable_chat_weblinks considers the . at the end as part of the URI, and opens http://wiki.minetest.net/Database_backends..
Note that using angle brackets (<link>) is sadly also not supported by clickable_chat_weblinks.

To do

This PR is a Ready for Review.

How to test

• Enable clickable_chat_weblinks.
• Open an old world, or migrate to old db backend.
• Open chat, ctrl+click the link.

At least xfce4-terminal does ignore tailing full stops automatically. Might it be a better idea to adapt the Minetest feature in this regard as well? I have yet not seen an URL that would end with a full stop.

Same for gnome-terminal, and (checks http://wiki.minetest.net/Database_backends. ) github under firefox.

Improving clickable_chat_weblinks would definitely be better. But I don't want to do this myself right now. Meanwhile this workaround also works.

IMO that should be fixed then. It's our own code.

@SmallJoker so what about your proposed patch? Why not push it (or open a PR if you feel it's nontrivial and there's something left to discuss)?
