extractEntryWithTmpFile throws NullPointerException when passing it a filename without any path

Pass new File("somefile.txt") to extractEntryWithTmpFile, run the program:

Exception in thread "main" java.lang.NullPointerException
        at java.io.File.<init>(File.java:239)
        at de.idyl.winzipaes.AesZipFileDecrypter.extractEntryWithTmpFile(AesZipFileDecrypter.java:206)

The code examination suggests that getParent() can return null if the filename 
of outFile doesn't have any directory. new File(null) then throws the exception.

// create tmp file that contains the decrypted, but still compressed data
File tmpFile = new File( outFile.getPath() + "_TMP.zip" );
makeDir( new File(tmpFile.getParent()) );
