Add a threat modelling tool

[AdSHSO]

Hi Team,

we have developed OVVL: https://github.com/OVVL-HSO/OVVL-Webapp

OVVL -> Open Weakness and Vulnerability Modeller

A STRIDE-based threat modelling tool that integrates CVEs. So you can do threat modeling based on STRIDE, but also analyse possible known vulnerabilities in case you already know off the shelf software components that may be used.

Best,

Andreas
