PARALLACTION: Flexible monologues in BRA (patch #3021740 by fuzzie)

Some dialogue answers are set to the literal 'null', which is used in NS to
simulate a fixed monologue ('null' instructs the engine to jump to the first
entry in the list of available questions, which is always made of a single
item in this case).
BRA has flexible monologues that depend on the game state, so this patch goes
and checks all the available branches before picking the correct one.
