BRA: always check dialogue flags
|Reported by:||fuzzie||Owned by:||peres|
BRA has several dialogues (eg, in stazione at the end of Part 2) with NULL answers which still have flags to check. This patch checks the visible answers and then picks the first one, which seemed the easiest way to check the flags. Patch seems to apply OK to trunk.
