TGEA 1.8.1 FileStream bug and fix.

If you supply ReadWrite as mode to FileStream and the path that you're trying to open doesn't exist, it won't create the path as it does when Write and WriteAppend modes are set. You'll run into an assert and Torque will quit.

FileStream.cpp @ 141

// IF we are writing, make sure the path exists
   if ( inMode == Torque::FS::File::Write || inMode == Torque::FS::File::WriteAppend )
	   Torque::FS::CreatePath(filePath);

Change to:

// IF we are writing, make sure the path exists
   if ( inMode != Torque::FS::File::Read )
	   Torque::FS::CreatePath(filePath);
