New topic button on every page

As discussed with @eulisse, it would be more intuitive to have a New topic button to every page (this is also to prevent people from replying to an existing topic instead of creating a new one, which is sometimes more appropriate).

I am trying to implement this solution, will report when done.

For the record, the aforementioned instructions only work for the default theme. We’d better change this theme and try to push our change upstream…
