Summary

Bugfixes "Fixes For Worn Enchanted Armor"

Purpose of change

Enchanted armor was broken when applying/removing traits. Also I have a desire to use the enchantment system for non magical armor. So to work towards more usability I've fixed some of the oddities.

The core issue is that when you trigger on_item_wear or on_item_takeoff you are still wearing the item that provides the traits so all of the recalculating that should happen gets done while you still have the traits

Easiest way to recreate this is try to put on an enchanted item that when worn gives Huge. Your Strength will keep scaling infinitely.

Describe the solution

This PR does the following

• Adds a vector for "mutations to add" and "mutations to remove" to the character object

• In on_item_takeoff and on_item_wear it just adds the relevant mutations to the relevant vectors doesn't do the calcs there

• Split all the repeated post calcs into their own function enchantment_wear_change

• In update body when the characters cached enchantments are recalced then the removed and added mutations are applied as well as the calls from enchantment_wear_change

• In the loop it also tests if you still have the mutation and if so doesn't run all the removal stuff. This would be for the situation where you have two items giving the same trait

• Needed to do some overloading of mutations_from_wearing so that you can specify your removing an item and further down the call stack ignore traits from items. This is because when doing the check for "hey did the player already have one of these mutations before putting on this item YOU ARE STILL WEARING THE ITEM SO IT SEES ITSELF"

• I've also added a new flag for items called "MUNDANE" it's for items with enchantments that shouldn't glow pink in the menu because they aren't magic.

• I've also added a rule so that if an item changes your size (makes you huge for example it doesn't push off the item that did it). This is for 2 reasons:

1. It supports armors like Power Armor not being able to be worn if your already huge but still lets them make you huge when you wear them
2. If this isn't in the game hard crashes on trying to do this under some circumstances.

Testing

Tested with a pair of earings jsoned to have:

"relic_data": {
  "passive_effects": [ { "has": "WORN", "condition": "ALWAYS", "mutations": [ "GLASSJAW" ] } ]
}

and a firebelt with:

"relic_data": {
  "passive_effects": [ { "has": "WORN", "condition": "ALWAYS", "mutations": [ "HUGE" ] } ]
},

glass jaw is great because its easy to test if your hp pool has updated on wearing and not wearing the item.
