Editor segfaults when saving in Linux

Hmmm... checking the Windows documentation it seems that the t flag exists and is called "text-mode translation flag". I searched a bit and I can't find anywhere saying it is available in Linux. On my computer fp returns NULL and the call to mxmlSaveFile(xml, fp, whitespaceCallback) with a NULL fp segaults.

Hmm... strange. I'm not able to reproduce this. I did notice that if you try to write to a directory you don't have permissions to write to (like /) then fp will be NULL so I think this patch is harmless and makes sure rocket doesn't crash if you have permission issues. The t flag does nothing in Linux so I guess we can remove it. But it doesn't seem to crash Rocket. 🤔 why was fopen() returning NULL to me ...
