Fixed a bug in the mac os X installer's "Choose Location..." dialog which _only_ let you choose directories, which is problematic for e.g. netbeans. Now you can pick any app, which isn't right either, but the mac's deplorable java filechoosers are to blame for this. I can't fix it, tried everything. This will have to do.
