[talk-au] source tags

[Andy Owen]

I tend to be quite lazy in tagging the source for the changes I make.
How bad a person am I? :)

When I add streets, I do it from gps traces so there is that evidence in
the database that the data was original.

Also, when there are streets that already exist, with a source tag and
I'm editing them, what should happen? e.g. lots of streets have the
source as the yahoo imagery, should I be 'upgrading' them to 'survey' or
'local knowledge' (as appropriate) when I'm modifying them?
