Make "quick acces" links between heading and TOC in the pgk page

@mnordahl As a web guru; could you perhaps tweak the scripting on the pgk page so that there is a one row quick link bar for the most common links such as [prog compendium] [dod labs] [kaptenalloc] [Sigrid] etc. The idea is that people with desktop and mobile quickly can get what they want if they are experienced users of the course material...
