be able to group ARs#61

when you have too many ARs, it gets confusing and messy. an option to be able to make a group and organize ARs accordingly when running .ar

an example could be:

to create a new group;
.ar group create moderation / for ARs that do mod commands
.ar group create currency / for server currency ARs

.ar group add currency .harvest / to add an AR to a group

.ar group move moderation .harvest / to move an AR to a group

right now, i just have a onenote document where i write my ARs and what it does so i dont forget
