Panel: NMEA Object Explorer

The NMEA Object explorer is a so called treeview.
It shows all available objects in the database grouped by type.
A group can be expanded or imploded with the small +/- box in front of it.
The following mouse actions can be performed on the NMEA Object explorer:
Note that deleting an object here will not ask for a confirmation.
When an object is opened it will disappear from the explorer treeview.
It will be placed back in the treeview when it is closed (from the tabbed interface).
