[jbosstools-dev] updated website docs

[Max Rydahl Andersen]

Hey,

Len's great work on a switchyard blog pushed me to update/add more docs 
for how to update/edit the website.

It's live on tools.jboss.org/survivalguide.html but probably better 
viewed/used on 
https://github.com/jbosstools/jbosstools-website/blob/master/survivalguide.adoc

Let me know if you find something missing or got a question about and we 
can add more to this doc over time.
