Subject: Cracking Office 2013 files with JtR

Hi,

I have added support for cracking Office 2013 files to JtR (magnum-jumbo).

Usage:

1. Build magnum-jumbo

2. Build office2john program by running "make office2john"

3. Run office2john on encrypted Office 2013 file

4. Run john on the output of office2john

Benchmark:

✗ ../run/john -fo:office -t
Benchmarking: Office 2007/2010 SHA-1/AES [32/64]... DONE
Raw:	38.6 c/s real, 38.6 c/s virtual

AFAIK, JtR might be the first software to support cracking Office 2013
files (at least Passware doesn't).

Note: To be really usable, we need an OpenCL implementation. magnum, Lukas?
