[OHM] sample filter test data - Maine

[Jeff Meyer]

Quick update here... I think I've finally put together some shapes that are
appropriate for Maine's history and given them some minor tagging.

ohm:2660783 <http://www.openhistoricalmap.org/relation/2660783> : Maine
District of Massachusetts (US Claim, 1783 (Treaty of Paris) - 1842
(Webster-Ashburton Treaty))
ohm:2668784 <http://www.openhistoricalmap.org/relation/2660784> : Disputed
Territory in Maine District of Massachusetts (UK Claim, 1783 (Treaty of
Paris) - 1842 (Webster-Ashburton Treaty))
ohm:2660785 <http://www.openhistoricalmap.org/relation/2660785> : State of
Maine (as of 1842 (Webster-Ashburton Treaty))

Of note, the Maine District of Massachusetts became the State of Maine in
1820 - the only thing that changed in 1842 was the Northern border. Not
sure yet of how to manage these types of changes to geo-object attributes
without time-based tags.

I've also tried to put some links to other data sources, such as Harvard
maps as a source, Mapwarper references for warped versions of the Harvard
maps, and wikipedia, where appropriate.

So... in theory... a filter that selects for 1800 should see the two claims
in Maine - UK and US, but not the current Northern border of Maine.
Likewise, a filter that selects for 1850 should just see the current
outline of Maine.
