?!help all to list all commands/provide link to wiki with list of commands

[Pagwin-Fedora]

this is based on a complaint about it being relatively annoying getting all the commands given you either have to go looking for the wiki or type out

?!help fun
?!help management
?!help misc
?!help moderation

ect. if we add more categories in the future alternatively we could have a ?!help all to list all the commands in one place or link to the wiki so you don't have to type all that out or go look for the wiki
