View source for Re: Empty body_r and body_toc

The installer empties ##body_r## and ##body_toc## because the toc and the headings along with other markup has changed. So every page must be recompiled, parsed again. 
  a. The ##show## handler recompiles a page if ##body_r## and ##body_toc## is not available (empty).
    * add a page reload condition, object cache issue?
    * need to test some cases to get a bigger picture
    * seems an object cache issue in ##built_toc## function
      * ##$page = $this->load_page($tag);##
  b. The Wiki-links option under Re-Synchronize data in the Admin panel re-parses all pages and updates the emptied ##body_r## and ##body_toc## fields,  as mentioned in the ((/Dev/Release/R5.5/Upgrade upgrade guide)). However there are some open issues:
    * the routine fails to continue if it can't parse a particular page or triggers an unwanted redirect
    * the page redirect may exceed the allowed value of your browser
    * the used routine settings may exceed your allowed system resources
    * the Wiki-links re-rendering option needs more testing and tuning, so far you can 
      * tune max records per turn
      * add an array to exclude failing pages in ##foreach## using ##continue##
      * turn on debugging, e.g. ##Diag::dbg('GOLD', $record, $page['tag']);## shows the last failing page

Fixes
  1. I fixed some ((revision:c3444ed issues)), excluded all system pages, but it should exclude only the pages failing to parse, and disabled the redirect action again.
  1. ((revision:f7e059d added option)) to re-compile all pages

Debugging:
  1. It seems that the ##changepassword## and the ##registration## action causes the routine to fail. WHY?
    * ##login## works. I assume both actions trigger a redirect.
