Update the Museum icon to be effective regardless of language

[quincylvania]

The current museum preset icon has an "M" character which does not make sense in most languages. We should find an alternative icon, preferably one that still indicates "museum" and not just some generic pillared building.

Do you think it can have any other form than this:

I agree - the "M" looks maybe too much like "Metro" station in many places.

I replaced it with the one we got from temaki (a generic pillared building for now, sorry 😂)
We were also using it for Planetarium preset, which I replaced with a globe.
