Ophcrack fix

Hello Isaac,

First of all, great work on the MultiCD project; I'm using it to create a bootable rescue hard disk. I realised that OphCrack wasn't on the list of supported distributions, despite having an ophcrack.sh plugin.
Turns out that it wasn't compatible with the latest OphCrack versions... so I've gone ahead and fixed the plugin. I've tested it, and it works now (I just made some minor changes). I've uploaded the fix to my forked repo.

Thank you,
Maxime
