What
Add second generic to MachineBuilder and reduce code duplication

go from
MachineBuilder<DEFINITION extends MachineDefinition> extends BuilderBase<DEFINITION>toMachineBuilder<DEFINITION extends MachineDefinition, TYPE extends MachineBuilder<DEFINITION, TYPE>> extends BuilderBase<DEFINITION>Outcome
No longer need to add a
public MultiblockMachineBuilder foo(Bar bar){ (MultiblockMachineBuilder) super.foo(bar) };for every. single. MachineBuilder. method.Additional Information
