Enhancement: Refactor functions for attacks and checks rolls

[PrototypeESBU]

Refactor and expand functions around attacks and checks to enabled easier changes and more useful for automation macros. Changes will allow for:

• Bonuses and advantages on all roll types.
• one or more selector components of the key path that will provide a scope of conditions that the change should apply to. ie. system.roll.{selector: melee|ranged}.advantage.{Selector: all|this|weapon_type|name_of_property}

List of new roll modifier AEs are listed here: https://github.com/Muttley/foundryvtt-shadowdark/wiki/API-Reference#roll-active-effects-keys
