Minor cleanups (#50)

* Finalize, minor alloc reduction

Also enable Jabel and generic injection

* Update dependencies.gradle

* Clean up Machine a bit

* spotless

more enhanced instanceof

* Update ModuleMachine.java

* More clen

* WARN: Removed exception catching

* Many, many tiny patches + birthday fix

* Spotless

* Spotless again

* Fix getLow and clamp tolerance value

* Revert event -> ignored on unused event parameters

* Rename instanceof variables

* Update Machine.java

* Use StringBuilder

* Cache getStack()

* Oops, Jabel can't handle that

* Spotless

* Spotless again

My IDE was fighting with it

* Remove unused elements + scream test success
