Add Insulative Filling that Can Be Used to Make Any Hat Psionically Insulative

[Dirius77]

About the PR

Provides a way to make any (non-armored) hat psionically insulative for those who don't like the look of the regular ones.

Why / Balance

Skullcaps look gross. Also it was requested by my bestie Pynter.

Technical details

Adds the system that the Bluespace Plushies wish they could be in the form of ModifyOnApplyComponent and its associated systems. I would transition the plushie patches to use it if it wasn't for the remaining bug in the Container/Inventory system that requires the plushies to do a special song and dance to make inventories work. Generally, the component will apply some components and possibly remove some from a target item that matches some set of: A Component Whitelist, A Component Blacklist, A Tag Whitelist, and/or a Tag Blacklist. (It uses its own tag component because TagComponent does not inherit from Parents and I didn't want to risk changing that, but that behavior means that any hat that applied tags after the fact would fail the whitelist check even if it really shouldn't)

I'd only make the fact that the hat is insulated more obvious, like changing the description and adding a little blip about the hat being stuffed with tin foil. alternatively making the name change be "psionically insulating x"

[Dirius77]

The names were getting to be too long on some of the hats with the whole thing, so I added the ability to modify item descriptions and added it like so:
