Addon Manager improvements

[furti]

I don't see where the links to the defunct repo come from

I hadva quick look. Problem is that there are some hardcoded links to the deleted repository in the readme.
They should be changed to relative paths i think.

This topic has gone so far beyond anything to do with being an announcement so I have locked the topic, here is a link a topic in the developers forum since most of these discussions seem mostly to be about development.

There is no point in us having an announcements and features forum if we are going to constantly hijack announcement topics with development, Help etc. as doing so defeats the point of an Announcements forum, i.e. attracting attention to something new.
