cache Fluid And PlayBlast 2.1.0 for Maya (maya script)

To make this work on windows the path used in the system command just needs to be modified like this (replace the system command with the two lines below):

        $playblastPath = toNativePath($imagepath + $fileNameSolo);
        system("mkdir \"" + $playblastPath + "\"");


This may or may not break compatibility with POSIX systems.  Also, the script should work just fine on Mac OS X as-is.
