Probabilities Output Option

[Vlek]

Feature request to add a command line flag, like -p/--probabilities, that will instead of rolling for a value, will output a list of all possible values and their percentage chance.

I.e.

roll -p 1d5
1: 0.20
2: 0.20
3: 0.20
4: 0.20
5: 0.20

I think that this would be an awesome addition but hard to implement, near impossible without duplicating a Lot of the parsing code right now. The only feasible way I can think of doing this is by adding the probabilities to the suggested EvaluationResults objects. That way it can calculate the probabilities as it goes through our current parsing methods without requiring any rewrite.

Things I have to look into further:

1. How will Keep notation effect this? Will it shift the probabilities up or down or something?
2. What about modulus and square roots? I think these sorts of things are going to throw me for a loop. Will likely change things such that I cannot notate things as a range as the numbers may become out of order.
3. I get that 1d6 + 1d6 is simply 2d6, but then how do we calculate something like (1d6 + 2) + 1d6? Or worse yet, 1d10 % 3 * 4d2?
