Add MS12-005 (CVE-2012-0013) exploit

[wchen-r7]

This module exploits a vulnerability found in Microsoft Office's ClickOnce feature. When handling a Macro document, the application fails to recognize certain file extensions as dangerous executables, which can be used to bypass the warning message. This allows you to trick your victim into opening the malicious document, which will load up either a python or ruby payload based on your choosing, and then finally download and execute our executable.
