[ticket/10973] Drop all require_once for mocks. Use autoloading.
[ticket/10973] Add autoloader for autoloading phpbb_mock_ in tests.
Conflicts:
tests/bbcode/url_bbcode_test.php
tests/text_processing/censor_text_test.php
Also made optionset use the value set by optionset. We're not checking
whether the option is set or not, because we would just throw an error
if it wasn't set, and it throws an error anyway.
