Fred roll X

Fred will return a number between 0 and X

The old Fred's behavior is here: https://github.com/SammyIsra/fred/blob/master/scripts/roll.js

However we might want to do it in a slightly different way. Old Fred's rolling was based on dice (roll 1d20, 2d100, etc). If we want to basically replicate the WoW one, the behavior is identical to roll 1d100 and there will always be only 1 die in the calculation.

Overall, it would be easier than old behavior.
