(closes#2633)
* move osmChangeJXON from osm service to osmChangeset
* cleanup putChangeset for code clarity
* adjust params for callbacks (pass changeset around instead of changeset_id)
* add commit.reset() to reset changeset object after successful save
* improve checks for changeset tags (trim whitespace, etc)
This is used to draw vertices
* where multiple parent ways meet
* where a single way self intersects (but not the closing node of a loop)
We were using Graph#isShared or osmNode#isIntersection, but this is slightly
different to handle self-intersecting ways.
I'm not sure why this is failing all of a sudden
I think iD.modeAddPoint was setting it up for other tests to use
iD.modeAddPoint needs to be commented out because of happen mouse handlers.
Not happy about all the side effects in our test suite :-(
