Magical fix for open project bug on linux

Well, fifteen minutes and some diffs and other boredom gets you this:

Open platformX86UNIX/x86UNIXFileio.cc and edit line 1167 [the Platform::dumpDirectories function].

Where it currently says

bool retVal = recurseDumpDirectories(path, "", directoryVector, 0, depth, noBasePath);

Change that to:

bool retVal = recurseDumpDirectories(path, "", directoryVector, -1, depth, noBasePath);

Yay for simple recursion bugs. Just change the zero to a -1.
This will also fix [by my count] two other obscure similar bugs.
