Make Fred a betting master 🎲🎲🎲

Resolves #20

This will allow for rolls in two formats.

DnD style rolling:

fred roll [3d]50

Where

• 3 would be the number of dice.
• 50 is the sides of the dice.

WoW style rolling:

fred roll [1] [100]

Where

• 1 would be the lower bound of the roll. Inclusive.
  • Optional. Default is 1.
• 100 would be the upper bound of the roll. Inclusive.
  • Optional. Default is 100. If only one value is provided, it will be the upper bound.

The most minimal version of the roll in WoW style is

fred roll

Since every other value is optional.

There are a few checks in place to make sure that the math is safe, and the regex make sure that the values provided are all valid numbers.

Thank you Adam for the regex!

I may have messed up in rebasing into origin/master. Closing this and reopening with new branch.
