OMG a ridiculous commit to overhaul import handler config etc.

- add `MasterView.configurable` concept, `/configure.mako` template
- add new master view for DataSync Threads (needs content)
- tweak view config for DataSync Changes accordingly
- update the Configure DataSync page per `configurable` concept
- add new Configure Import/Export page, per `configurable`
- add basic views for Raw Permissions
