An expansion of loot types and ego affixes

A fork of Wayback's loot expansion (https://te4.org/games/addons/tome/loot)
Thanks Wayback for creating the original addon.

Adds the 'Runed Shield' ego for shields, which grants a chance to cast spells on block. This can only trigger once per turn.

Modifies mastery and perfection egos to only roll from what you have unlocked and have at least 1 point in, to reduce useless rolls.

Add regular weapon egos to mindstars.

Not complete. Please don't use yet unless you want to beta-test an incomplete addon.

Contains replacements for existing egos.

Summary:
- Rebalancing pretty much all item type egos.
- Some replacements, some removals, a few additions.

Adds one new unique enemy, one new artefact, and two new greater egos to the game. This mod is designed to give Marauders more variety and make them more interesting to play. The Egos both provide the Skullcracker Multiplicator bonus, as does the new artefact, and the new unique enemy has a high chance to drop the new artefact. He can appear in any of the starter dungeons, but will most frequently appear in Heart of the Gloom or Norgos' Lair.
