Modifier is always 0

[Heilemann]

When rolling e.g. 1d6+2 I take the +2 to be a modifier.

The parsed roll object has a key named modifier, but as far as I can tell it's always simply 0. I assume this is supposed to be e.g. 2 in the case of the above roll (although I can find no documentation of the roll object or its types)

Although the modifier is ultimately also represented in the dice-box results object, it would make sense for it to also be represented in the parsed roll object, for the purposes of displaying rolls and their component pieces.
