Fixes Enum Duplication Issue

[KAMKEEL]

Adds Enum Map to keep track of all Enum Names associated with their Enum Classes

• $1, $2, $3, $4.... and so on will be appended to the Enum Name until the Duplication clause is satisfied.

The issue in detail is explained here: #115
The enum names are case-insensitive when they are registered so all enums capitalized before comparison

To elaborate on the case sensitivity issue, there's a mod called SkyForge ^{(PlanetMinecraft | DDL)} that registers the tool material name Glass. Before the code was made case insensitive, this still conflicted with Kam's Plugin Mod v5.2 which registers the name GLASS. (The materials are used by the Glass Sword and the Glass Dagger respectively.)
