feat: slashcommands for showall, findplayer, get/openhttpmoninfo, and debug world packet (#1545) 
* feat: showall, findplayer, get/openhttpmoninfo

http monitor info is planned to be used later, just putting in info that i've since reverse engineered and don't want lost

Additionally add debug world packet for duture dev use

Tested all new commands and variation of command arguments

* fix missing newline at eofs

* address most feedback

* Compormise and use struct with (de)serialize

* remove httpmoninfo commands
