feat: refactor slash commands system into more scalable system

[aronwk-aaron]

Spot checked a several of the commands. Things still work and there is a new help command. A bulk of the changes are breaking up the big if-else-if block into functions and registering each command.

Future PR will break out each set of command into it's own file. (dev, gm zero, and gm greater than zero command)

Note to self: fix failing test

Thanks emo

OKAY, this is the final form of this PR, I need to check some things with the help command not displaying correctly in-game that may be due to some char limit of that message, but that's a tangent. General feedback and suggestions welcome. Emo help me with this impl, so I may need to refer to him for some questions

Declining to review since I contributed to the pr and am biased. I will keep cleaning it up and helping work on it though

text prints correctly and utilizes the asterisk found in reverse engineering. Its used for denoting where a localized string starts and ends.

Edit: I see the weirdness... not sure why its repeating the last chunk of text for large strings

afaict, we are sending the correct data, however whats being printed is not correct. Will have to debug further to figure out the issue.
