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!

{if},{elseif},{else}
{if} statements in Smarty have much the same flexibility as PHP
if statements, with a few added features for the
template engine. Every {if} must be paired with a matching {/if}.
{else} and {elseif} are also permitted. All PHP conditionals and
functions are recognized, such as ||, or, &&, and,
is_array(), etc.
If securty is enabled, only PHP functions from $php_functions property
of the securty policy are allowed. See the
Security section for details.
The following is a list of recognized qualifiers, which must be separated from surrounding elements by spaces. Note that items listed in [brackets] are optional. PHP equivalents are shown where applicable.
