Still using http:// for xxx.edgewall.org in code and documentation

[Dirk Stöcker]

There are many places in code and doumentation where for links to (www|trac).edgewall.org still http:// is used.

The site edgewall.org already redirects http to https, so please replace any place in whole sources with https:// usage.

This probably is a good idea for other sites as well, but for edgewall it is most obvious and needs no additional checks.

My suggestion is to find all places using http:// links and check if they can be redone to use https:// instead, but that's more work.
