OE - Add list of loaded objects per package/level

[juso40]

As a mod author, I would like to know what objects are loaded at all times. For this, a list of packages/levels in each object's dump could be useful. Obviously, this would need a few blacklisted objects, e.g., SkillsDefinition, Meshes, Materials... that are only part of a character package.

Another nice addition would be to allow filtering for certain packages in the search. For example: inclass:SkillDefinition package:Sanctuary_P This would search for only SkillDefinitions that are loaded in Sanctuary. Similar, this could be expanded to allow for a list of packages or even for All which would need to internally match all level packages to work correctly.
