Persist Perspective viewer state including column formatting

Browse Source 
Save/restore went through both viewer and plugin, where the explicit
plugin.restore could stomp the column formatting the viewer had
already applied. Capture via viewer.save() alone (it includes
plugin_config) and restore via a single viewer.restore call with
edit_mode merged in. Added a perspective-config-update listener so
formatting, sort, and other in-place changes persist to the last-used
cache without an explicit Save.
