map_update binaries

[Dune-jr]

Seeing how many people ask for a compiled version of map_update, and waiting for a release, I'd like to post them here so they can be easily linked. I will remove the links once there is a proper release.

• map_update (linux_x86_64), at 5863884

Thanks!
I still want to change a few tiny things, but I'll try to release a stable version at the end of the week.
