Javadocs, cleanup, extension's client rules, built-in BundledModules generators, etc (#544)

* Add javadocs to many methods

* Added built-in ways to generate BundledModules and documented them

* Add Eclipse launch files to .gitignore and fix 11 warnings

* Remove many unused imports

* Remove some dead and unused code around app loading

* Allow extensions to have client-side rules in their SettingsManager

Also change tabs to spaces when those changed

* Remove unnecessary classloader param in BundledModule

* Change max tickwarp duration to Integer.MAX_VALUE

* Move RulePrinter into the source so it can be managed by the IDE

* Properly reset hopperCounters when changing worlds

Also change tabs to spaces again and minor tweaks to javadocs

* Run mergedocs even if Full.md was modified

* Update src/main/java/carpet/commands/TickCommand.java
