Add support for A Happy Assembly

[LoisGNS]

The main URL where stories are found is: https://meryton.com/aha/index.php?/forum/47-completed-stories/. I think login is necessary to read stories, but I understand FFF supports adding login info into personal.ini. Currently, one can save stories manually (copy/paste into a Word or other document). Some use multiple linked pages, which FFF would need to find and pick up.

Thanks for anyone who can do this.
