Refactor dice rolling to be less fragile

[OtherwiseJunk]

Currently we're referencing form elements to extract information, we should be extracting it from the character's data directly or referencing the HTML elements more precisely.

This is the readout of the htmlElement.form object, should be able to just select the inputs of the values to get the dropdown values and then continue to look it up in the rollData object

Just use the this.actor.system values dummy
