   4    dynamic plugin loading
   5    ����������������������
   6    Will load plugins on demand, so they must not be included() one by one
   7    together with the core script. This is what commonly the "plugin idea"
   8    suggests, and only has minimal disadvantages.
   9    - This loader currently only handles "page" and "action" plugins,
  10      many other extensions must be activated as before (the other ones
  11      are real functionality enhancements and behaviour tweaks, so this
  12      approach really made no sense for them).
  13    - There is no security risk with this plugin loader extension, because
  14      it allows you to set which of the available plugins CAN be loaded
  15      on demand (all others must/can be included() as usual elsewhere).
  16    - This however requires administration of this plugins` configuration
  17      array, but that is not much more effort than maintaining a bunch of
  18      include() statements.
  19    - Is a small degree faster then including multiple plugin script files
  20      one by one. Alternatively you could also merge (cat, mkhuge) all
  21      wanted plugins into one script file so you get a speed improvement
  22      against multiple include() calls.
  23    - Use tools/mkpluginmap to create the initial plugin list.
