What does this pull request do?

Replaces item IDs with item enum names.
Adds missing items to item enum lua.
Fixes BRAVURA_119_III enum using incorrect item ID.

NOTE: I noticed when swapping out the Item IDs that Homam legs are included in the artifact range? I have not looked into this further at this time on how this table is used exactly. Left a note in place.

Steps to test these changes

Item Enum should match Item ID. No changes should be noted from existing enum usage aside from BRAVURA_119_III which was incorrect.

I get these are only ranges, but could you stylize this a bit to align beginning and end for the rows?
