Addition of a display list command to display all available guilds

Such as /bclaims guild listall

There are a bunch more commands that I would like to add, such as bclaims guild leave and bclaims guild list. At the moment I am just adding the needed commands for the main features and once that is done I will flesh out all commands

Also a member list would be good, such as /bclaims guild "namehere" members - etc...
