new addon: vwhl - void watch highlighter

This plugin redirects the vw nm's vulnerabilities to the "tell" stream so that they can be held in the chat log using the chat filters' hold function (Config > Chat Filters > "Enter" on "Tell" until you get the green "hold" icon).
Moreover, the important informations are highlighted and a number is added to quickly understand the vulnerability level (1, 3, 5).
Supports EN, FR, DE clients.
