[doc] change doco title to "Tablicious" from "Octave Tablicious", bc …

…this is *for* Octave, but not actually a GNU Octave project

Also, it makes the truncated page title display in browser tabs for the multi-page HTML format more distinctive.

Tweak some other wording while in there. Fix the GitHub Project link for my recent migration to their new format. Add more "GNU"s, to be respectful.
