[Suggestion] Move away from enums

[idcppl]

Is your feature request related to a problem? Please describe. A lot of the material system is attached to enums that dev's are forced to use EnumHelper for. In example,

• https://github.com/GregTechCE/GregTech/blob/master/src/main/java/gregtech/api/unification/material/MaterialIconSet.java
• https://github.com/GregTechCE/GregTech/blob/master/src/main/java/gregtech/api/unification/material/MaterialIconType.java
• https://github.com/GregTechCE/GregTech/blob/master/src/main/java/gregtech/api/unification/ore/OrePrefix.java
• https://github.com/GregTechCE/GregTech/blob/master/src/main/java/gregtech/api/unification/Element.java

Describe the solution you'd like To move these over to registration maps.

If you are going to do this, then you need to make sure that things that depend on the ordinal still work as before.

e.g. the order that OrePrefix handlers are run
