chore(core): deprecate prefixed accessors/mutators in CommandManager.java
All prefixed (actual) getters/setters in CommandManager have been deprecated, and non-prefixed alternatives have been introduced. I've also put some effort into improving the JavaDocs of these methods.
* build: switch to spotless
add in some other basic formatting steps that allow for easy
auto-correction
* build: lint text files as well
* chore: remove license headers from package-info files
spotless can't verify these
* fabric: Update Loom to 0.7-SNAPSHOT
* Update to Gradle 7
Switch to CadixDev/licenser
The plugin we were using before does not support Gradle 7, and hasn't been updated in over a year.
* Remove `jcenter()` references
* Move to new JDA repo and bump version
* Use setup-java v2 and Adopt JDK 16 in gh actions
* build: Temporarily add Incendo repo for plugin resolution
Allows building until licenser has a new release
* Import indra plugin classes instead of string applies
* remove space

Conflicting commands will now obey plugin load order. Brigadier aliases will be created for namespaced aliases. No asynchronous completions will be provided for conflicting commands and will only be provided for the namespaced label. Furthermore, error handling the command tree has been improved and the methods now return a pair, rather than an optional. This means that there's no need to catch and unwrap exceptions and they will be forwarded in the correct form.
