Dispel magic!

[supersaiyansubtlety]

This PR eliminates automatic installation of components and listeners and generally tries to reduce the amount of "magical" side-effects-based behavior.

This makes things more customizable and easier to follow.

Can be tested by publishing locally and checking out QuiltMC/enigma#317

Remaining magic:

• JavaLexer: it's generated by jflex; that's just fundamentally how it works
• JavaSyntaxKit is still installed to make editors use SyntaxViews and SyntaxDocuments;
  AFAICT there's no way to manually attach a different ViewFactory to an editor without completely replacing its TextUI which would also replace all the functionality of the UI installed by flatlaf.

Also:

• allows offsetting LineNumbersRuler's numbers (for use in tooltip snippets)
• removes a few instances of setting colors and fonts in favor of setting them in enigma
• removes SyntaxpainConfiguration but adds JavaSyntaxKit::setSyntaxColors for SyntaxStyle; keeping this is necessary because JavaSyntaxKit is still magical
• removes a couple classes that were only necessary for magic or whose functionality made sense to move to other classes
