Macro: Party Tests

[Jagusti]

Add macro for the GM to make a test for the whole party. Primary use case is secret Perception tests.

In the first instance, this might just be a basic Perception test, with no modifiers, run against all PCs that are active in the game or associated with players.

Fancy version might be

• add option to run silently (based on specified parameters) or interactively
• Set up group selection and filtering #61
• optionally make Public roll (default: Self)
• Secret Party Tests: Aggregate party skill check results #62
• Secret Group Tests: Add user interface to select and configure secret skill check parameters #63
• Secret Party Tests: select relevant talents #64

Possible checks:

• tests related to Flag 'passive' talents on tokens #26 'passive' talents
• From @SeanPP: Intuition, Track, Secret Signs, Sleight of Hand
