Update FormHelper::error() to reflect current implementation.

Use templates for HTML generation instead of attribute/array smashing.
This will break existing use cases, but I honestly doubt people use many

defaults, or copy and pasting formatting options everywhere.

* ### Options:
*
* - `escape` boolean - Whether or not to html escape the contents of the error.
* - `wrap` mixed - Whether or not the error message should be wrapped in a div. If a
* string, will be used as the HTML tag to use.
* - `class` string - The class name for the error message
*
* @param string $field A field name, like "Modelname.fieldname"
* @param string|array $text Error message as string or array of messages.
* If array contains `attributes` key it will be used as options for error container
* @param array $options Rendering options for <div /> wrapper tag
* @return string If there are errors this method returns an error message, otherwise null.
* @param string|array $text Error message as string or array of messages. If an array,

* @param array $options See above.
* @return string Formatted errors or ''.
