I've decided to overhaul the implementation of DiscordToMinecraftListener to make it more easily workable. This overhaul allows me to implement FS-215 more easily.
Credit to Fleek for some of the code here.
Bugs that were fixed:
* [Media] showing up with an extra space at the beginning of blank messages with attachments
* Admin chat using incorrect colors for its ranks in messages from Discord to Minecraft
* Admin notes not sending to admins, only admin impostors
SplittableRandom is faster (negligable) than Random and is also able to recursively return new instances of itself for an even more complex pseudo random generator compared to the default Random supplied by Java.
These fixes are designed to satisfy codacy.
However, codacy reports a NPath Complexity of 649, whereas the current, recommended, and standardized threshold is 200.
This is caused by FreedomCommand#execute(CommandSender, String, String[]);
Lombok implementation removal.
I have also gone through and replaced things with inline methods and variables, lambdas, and simplified loops down, removed unnecessary guard clauses, and overall cleaned up every single class. This took a long time, please do remember to follow proper naming conventions, don't include unnecessary guard clauses, follow exception rules and comment rules, and please PLEASE remember to use the DIAMOND OPERATOR rather than just inferring RAW TYPES!!!
Thank you!!
* rename everything containing staff back to admin (as requested by ryan i've renamed commands like slconfig to saconfig but left "slconfig" as an alias)
* format almost every file correctly
* a few other improvements
