Allow reporting bugs directly from minetest.
A nice idea!
But how should responses reported?
The messages would be delivered into minetest or an e-mail address needs to be registered and verified as connected with a minetest player.
And I think that responses only into a minetest server is a bad idea, because a server can for different reasons (eg. pseudo-backups and "restoring" from them) be out of service or a player not anymore playing on that server (lost interest, ban, ...).
