RandomQuote provides the user with the ability to create multiple random quote "pools" to send to the /yell channel.
Slash command usage:
/randomquote add <quote> -- add a quote to the current quote pool
/randomquote list -- list all quotes in the current quote pool
/randomquote remove <index> -- remove the quote with the ID <index> from the current quote pool
/randomquote table <name> -- switch to a different quote pool
/randomquote tablelist -- list all available quote pools
/randomquote <anything except the above> -- /yell a random quote from the current quote pool
