CreateBatchFiles should create directories for the output file.

[DavidStirling]

Currently CreateBatchFiles does all it's processing, but then fails to write the batch file if the directory the output is set to does not exist. I think this may be because the file name widget is set up as a text entry rather than a proper directory widget. We should fix that at some point.

Either way, I should be able to say "save to \project\batchid\file.bat" without it failing just because the \batchid\ folder doesn't exist yet.
