Merge remote-tracking branch 'origin/develop' into feature/tree-consolidation
Add `attributes` to join models and a few fixes
Remove 'debugger' statement
Make RequestQueueManager to handle aggregating requests

* can now accept requests from multiple 'RequestQueues', combine
  the requests to minimal hits on each endpoint, and return the
  correct set of objects to each queue listener
Ensure Section is Personable and Documentable
Merge remote-tracking branch 'origin/develop' into feature/tree-consolidation
Ensure modal is removed from DOM after 'hide' event
Move 'computed_errors' to be function rather than attr
Multi-type selector now uses same JoinDescriptors as LHS

* also added support for 'People' options
* deprecated 'modal-selector-dispatch'
Consolidate trees and add new mappings Model attribute

* Model.mappings specified a set of relationships to be lazily
  collated into a list of { instance: <>, mappings: [<>,...] }
  objects -- this was needed to enable unmapping from trees
* Added various markup in trees to support unmapping and sometimes
  not showing +Object areas
* Added a variety of Model.attribute entries, since these seemed
  to resolve some errors and speed some things up
Add the actual 'unmap' button handler
Change lists mapped via 'Relationship' to use TreeView

* add 'widget_initial_content' to DashboardWidget
* change 'related' list loader to use can.Construct and be much more
  complete
Add many entries to Model.attributes for many models

* this appears to drastically decrease the number of 'change' events
  sent through the system during object loading
* also tried to unify the order of attributes / defaults, but needs more
* !! removed several published attributes from Control endpoint
  -- this significantly speeds up Control object loading
Remove some console.debug statements
