[OHM] simple way to move a building from OSM to OSM

[SK53]

The simplest way is to select the object(s), create a new layer & COPY them
into the layer which will create new objects. I think the process is noted
in my City Stripping
<http://sk53-osm.blogspot.com/2014/12/city-stripping-building-historical-road.html>
blog post.

For now I'd discourage using OHM as a backing store for demolished OSM
buildings (not least, because the data is in the OSM history). At the very
least avoid doing it on a large scale.

We would quickly be overwhelmed if every deleted object from OSM got pushed
into OHM immediately. On the other hand things like the London Olympic Park
from 2012 which has changed significantly would be something worth pulling
into OHM. At present we need coherent data sets (typically project based),
so if you want to find 5 years of demolished buildings from a discrete area
in OSM and place those in OHM this would give us enough data to explore
what the issues are with the generic case (pulling all dead OSM buildings
out).

Also for now until we get a better conceptual grasp most of the OHM data is
a snapshot at a particular notional date.
