flatpress/fp-includes/smarty-4.0.4/libs/plugins/modifier.regex_replace.php
azett 52bf429a01 Replaced Smarty 2.6.31-dev with v 4.0.4, keeping the FP-specific Smarty plugins.
Updated calls to current Smarty API (register_function()/register_modifier()/register_block() -> registerPlugin(); assign_by_ref() -> assignByRef()).
Fixed file includes in templates with quotes.
Removed SmartyValidate.class.php includes.

Still work in progress as some errors still appear!
