[Talk-ca] Removing source=* when editing

[Nate Wessel]

Agreed.

I'm sometimes even a little more aggressive, especially when dealing 
with geobase street imports. The "attribution" field can also safely be 
dropped, IMO,and so can fields like "geobase:acquisitionTechnique 
<https://wiki.openstreetmap.org/wiki/Key:geobase:acquisitionTechnique?uselang=en>" 
and "statscan:rbuid", especially if the geometry has changed.

I'll sometimes merge segmented streets like this one 
<https://www.openstreetmap.org/way/36820145> into one geometry, if all 
the other meaningful tags are otherwise the same and drop those fields 
that were created just for the import.

It's all still there in the revision history, but it makes the current 
data easier to work with.
