 - monitoring.widget.navigationtree.view => monitoring.widget.navtree.view
 - monitoring.widget.sysmap.view => monitoring.widget.map.view

Actions and widget types:
 - widget.actlog.view => widget.actionlog.view
 - widget.dscvry.view => widget.discovery.view
 - widget.favgrph.view => widget.favgraphs.view
 - widget.favmap.view => widget.favmaps.view

Added database upgrade patch to rename old widget types by new types.

Refactoring:
 - widget refresh rate controller accepts only one widget instead of array of widgets
