BRA: don't display null strings
|Reported by:||fuzzie||Owned by:||peres|
This 'short-circuits' the dialogue loop for when an answer is 'null' in order to jump to the next answer immediately, to stop scummvm from displaying 'null' inside balloons. You can see this in a lot of places in BRA, for example examine the money in your inventory.
Patch seems to apply fine to trunk. I don't know if this might cause problems for NS or there's something I missed, though.
