# The Card#abort method is for cleanly exiting an action without continuing
# to process any further events.
#
# Three statuses are supported:
#
#   failure: adds an error, returns false on save
#   success: no error, returns true on save
#   triumph: similar to success, but if called on a subcard
#            it causes the entire action to abort (not just the subcard)
