further update to global memory cache arrays

- remove initialisation of caches in inc/pageutils.php
- add global declaration to init.php to support init.php
  being included from within a function, e.g. unit testing

  ;-)

- minor change to utf8_substr, remove non-essential brackets
  added as part of an earlier patch
