[Tagging] building=digester

[Marc Gemis]

Triggered by a discussion on the Dutch forum I looked at the building
page  [1] again. I noticed a new value: digester

I wonder whether it wouldn't be better to put this under man_made [2]
just as we do with gasometer, hot water tank and similar constructions.

what do you think ?
