Updating attribute calculation to look at all equipment #8188 (#8202)

* Taking all equipped items into account when calculating attributes instead of just head, weapon, sheild, and armor. closes #8185

* Refactored the stat calculations a bit so that all stat calculations are handled in the same location in the same way to try and reduce duplicate logic.
This commit also adds a number of tests to test this new behavior.

* spelling fixes
