* Create a nwe AddressAndMapLocator which abstracts out the behavior of
selecting a location
* Fix the overlay causing render errors on the MapLocator by getting
rid of the overlay and just using a lock indicator
* Fix MapLocator zooming in to the wrong place by not framing the
markers
* Remove Latlng from platform and just use Location with optional
accuracy
* Use nested types with form-encoded POST
* Fix styles on water report page
This refactor was born out of the inter-dependency cycles developing
between the "background" module and just about every other module which
was caused by the background module becoming a dependency of every
module that needed to background work and the fact that the background
module was also supposedly responsible for the logic for processing
those tasks.
Instead the "background" module is now very, very shallow and relies
entirely on the Postgres NOTIFY logic for triggering jobs. There's a new
table, `job` which holds just a type and single row ID.
All told, this means that jobs can be added to the queue as part of the
API-level or platform-level transaction, ensuring atomicity, and
processing coordination is handled by the platform module, which can
depend on anything.
This involved moving a lot of stuff to the platform layer since I don't
want event interfaces leaking out.
Also this includes a fix to the user authentication which I had
previously broken by making a platform-layer user object independent of
the database layer.
This adds the ability to link a proper address in the database to the
report and harmonizes the field names with the address table. It also
migrates away from mapbox entirely.
And I fixed the "pool" naming for the publicreports, which are supposed
to be the more generic 'water'.
