Do not show subclass entries as armor in Clustering and Armor Investigation

[Mijago]

Currently, subclass entries are shown as armor in the clustering and armor investigation pages. Solving this should be easy: just filter them out when you update the inventory or manifest.

From a Discord-Ticket:

Hi, I believe character subclasses are not being filtered out of "armor clusters" under the clustering tab. I noticed this because I have a cluster with 17 pieces of very low stat armor but when I copy over the DIM query it shows two armor pieces I have and then 15 subclasses across all three characters. (See pics).

Large progress towards this issue, still a nightmare to work through everything

All possible "first plugs" documented, all that has to be done is to ignore entries with the plugs used.
