Update docs to reflect removal of legacy add-on support about developer-docs

@PaulMorris We should probably make sure to announce this on the appropriate mailing lists too!

I started to work on a re-ordering of the addons section a couple of weeks back, but it was too much for me. The draft is still in gitbook but I think no longer merge-able, as so much has changed in between.

I do believe, that we should seperate core dev and addon dev more obviously as it is done now. So if you start to shift things around, maybe have that in mind as well?

@clokep Good call. I have just sent an email to tb-planning and the TB addons lists.
@jobisoft Is there somewhere I can see your draft work on a re-ordering? I'd like to at least see where you were going with it, in case I find time to work on this.

@PaulMorris : You need to log into gitbook. Ryan can give you access if you do not have that.

In the top left you should see my draft under "edits".

@PaulMorris : My main idea was to have only two main sections (core and addon). I do not think it is mergeable, as so much changed in the core section and i do not know if gitbook can cope with those when I moved everything around.

[jobisoft]

@PaulMorris : My draft is actually loaded in the screenshoot above, so you can see my concept there already.

Thanks @jobisoft , that's helpful. I'm going to work on this now. Probably won't get into the re-arranging, just the updates to the addons info.

We forgot to close this. DTN has been updated.
