Gamble Class Items for D2RMM

See the REAME.md for details.

Source code is here.

This mod makes class-specific items available for gambling. (Assassin katars can already be gambled.)

If `Amazon` is enabled, then Amazon-specific bows, spears & javelins can be gambled.

If `Barbarian` is enabled, then Barbarian-specific helmets can be gambled.

If `Druid` is enabled, then Druid-specific pelts can be gambled.

If `Necromancer` is enabled, then Necromancer wands and heads can be gambled.

If `Paladin` is enabled, then Paladin scepters and shields can be gambled.

If `Sorceress` is enabled, then Sorceress staves and orbs can be gambled.

If `Warlock` is enabled, then Warlock grimoires and dagger can be gambled. If you do not have the Warlock DLC, this option has no effect (and daggers can normally be gambled).

If `Only add normal items` is enabled, then only normal items - not exceptional and elite item type - will be added to gamble.txt.

This is the way other items are put into gamble.txt, but may need to be disabled if there is a problem

with the normal -> exceptional -> elite progression for some class-specific item type.

If `Change gambling odds` is enabled, then the chances of a gamble being rare/set/unique are greatly increased,

as well as the chances of an exceptional or elite upgrade.

The `GambleUnique`, `GambleSet`, `GambleRare`, `GambleUber` and `GambleUltra` settings allow fine tuning of the gambling odds.

See https://classic.battle.net/diablo2exp/basics/gambling.shtml for more info.

If `Fix Cow King set drops` is enabled, then a bug is fixed that prevents Cow King himself from dropping items of the Cow King set.

If `Fix Countess rune drops` is enabled, then the Countess-related treasure classes are fixed to make her prefer dropping runes over items (except sunder charms).
