- This commit adds a proof-of-concept for retrieving actor template
types. These are actors using the `worldbuilding.isTemplate` flag set
to true. If there are multiple actors with that flag set to true,
clicking the create actor button will pull up a prompt to choose from
one of those types, which will then create an actor by duplicating
the template actor's data. The flag will be unset on the new actor.
- Added a resource attribute type to both actors and items with the keys
min, value, and max.
- Added translation strings for the sublabels on resources.
- Adjusted styles of item buttons.
- Fixed an issue with item buttons when not using shorthand syntax.
- Updated the `roll.toMessage()` call to include the player/actor name
and the item/attribute name.
- Utilized the revisions made to roll syntax to allow for rollable
buttons on item lists on actor sheets. Rolls are evaluated using
`@items.ITEM.KEY`, where ITEM is the item name (slugified), and KEY is
an attribute key for a formula attribute.
