Extract generated HTML code to template files

[Taitava]

src/CloakingModes.php contains some inline HTML code that should not be there:

<?php
namespace Taitava\CloakEmail;
class CloakingModes
{
	public static function none($value)
	{
		return $value;
	}
	
	public static function nojs($value, $options)
	{
		$address = str_replace(array('.', '@'), array($options['dot'], $options['at']), $value);
		if ($options['insert_link']) return "<a href=\"mailto:$address\">$address</a>";
		return $address;
	}
	
	public static function simple($value, $options)
	{
		CloakEmail::RequireJavaScript($options);
		$address = str_replace(array('.', '@'), array($options['dot'], $options['at']), $value);
		if ($options['insert_link']) $address = "<a href=\"mailto:$address\">$address</a>";
		return '<span class="simple-cloak">' . $address . '</span>';
	}
	
	public static function hard($value, $options)
	{
		CloakEmail::RequireJavaScript($options);
		$noscript = '<noscript>' . $options['hard_noscript_error'] . '</noscript>';
		$chars = array();
		for ($i = 0; $i < strlen($value); $i++)
		{
			$char = $value[$i];
			$chars[] = ord($char); //Convert the character to a decimal number
		}
		$insert_link = $options['insert_link'] ? ' insert-link' : '';
		return "$noscript<span class=\"hard-cloak$insert_link\" style=\"display: none;\">" . implode('-', $chars) . "</span>";
	}
}

One particular issue is that <a href="mailto:...">...</a> elements cannot be customised. If all HTML snippets would be in .ss template files, they could be overridden by a developer just by creating another template files.

So in summary, these three types of HTML snippets should be extracted to separate .ss template files:

• <a href=\"mailto:$address\">$address</a> (see also the special insert-link case in hard())
• '<span class="simple-cloak">' . $address . '</span>' (only in simple())
• '<noscript>' . $options['hard_noscript_error'] . '</noscript>' (only in hard())
