[HOT] Alignment to NextView in Job #190

"NextView" imagery is an old term we used to reference imagery services
provided through MapGive / Imagery to the Crowd (IttC) by the U.S.
Department of State, Humanitarian Information Unit (HIU).

Generally speaking, HIU imagery services and Bing are BOTH orthorectified.
I'd align your imagery to the existing roads (regardless if these roads
were originally added through Bing or MapGive imagery services), since
Kathmandu is already so well mapped.

This is an old task, so you can ignore the source=NextView request.  We
only need the commit message to include #MapGive (as it does by default).
Thanks for your contribution to the Nepal Earthquake response.
