Allow .roll to roll an arbitrary die

[EmberHeartshine]

At the moment .roll only rolls 1d100 for Best Pony purposes. I propose an optional argument of ndy, where n is the number of dice to be rolled and y is the number of faces on the die. Adding the argument will not trip Best Pony detection at all (nor be tracked for Best Pony purposes), unless it is exactly 1d100.

Thinking of working on Izzy again, this seems like a good "first after not working on the bot for a while" feature request.

Should a basic amount of math be implemented? Such as 1d6+3 (where a 1d6 is rolled, then 3 is added to the result) or should we stick strictly to ndy?

If it's simple to add, sure. Otherwise I wouldn't bother. (eg. more complex rolls involving multiple dice etc is not necessary)
