Tags with setOptionValidator do not run uppercase tags through the validator.

[BenFenner]

Steps to reproduce:

1. Have these code definitions set in DefaultCodeDefinitionSet.php:

    // [color] color tag
    $builder = new CodeDefinitionBuilder('color', '<span style="color:{option}">{param}</span>');
    $builder->setUseOption(TRUE)->setOptionValidator(new \JBBCode\validators\CssColorValidator());
    array_push($this->definitions, $builder->build());

    // [size=3] font size tag
    $builder = new CodeDefinitionBuilder('size', '<font size="{option}">{param}</font>');
    $builder->setUseOption(TRUE)->setParseContent(TRUE)->setOptionValidator(new \JBBCode\validators\FontSizeValidator());
    array_push($this->definitions, $builder->build());

2. Have these validators: CssColorValidator.php

<?php

namespace JBBCode\validators;

require_once dirname(dirname(__FILE__)) . DIRECTORY_SEPARATOR . 'InputValidator.php';

/**
 * An InputValidator for CSS color values. This is a very rudimentary
 * validator. It will allow a lot of color values that are invalid. However,
 * it shouldn't allow any invalid color values that are also a security
 * concern.
 *
 * @author jbowens
 * @since May 2013
 */
class CssColorValidator implements \JBBCode\InputValidator
{

  /**
   * Returns true if $input uses only valid CSS color value
   * characters.
   *
   * @param $input  the string to validate
   */
  public function validate($input) {
    return (bool) preg_match('/^[A-z0-9\-#., ()%]+$/', $input);
  }
}

FontSizeValidator.php

<?php

  namespace JBBCode\validators;

  require_once dirname(dirname(__FILE__)) . DIRECTORY_SEPARATOR . 'InputValidator.php';

  /**
   * An InputValidator for font size values.
   */
  class FontSizeValidator implements \JBBCode\InputValidator {

    /**
     * Returns true if $input uses a valid font size value.
     *
     * @param $input  the string to validate
     */
    public function validate($input) {
      return (bool) in_array($input, array(1, 2, 3, 4, 5, 6, 7));
    }
  }

3. Place text like this in an appropriate test input:

[SIZE="8"]Uppercase SIZE "8"[/SIZE]
[size="8"]Lowercase SIZE "8"[/size]

[COLOR="!@$%^"]Uppercase COLOR !@$%^[/COLOR]
[color="!@$%^"]Lowercase COLOR !@$%^[/color]

4. Notice this inconsistent output:

<font size="8">Uppercase SIZE "8"</font><br>
[size=8]Lowercase SIZE "8"[/size]<br>
<br>
<span style="color:!@$%^">Uppercase COLOR !@$%^</span><br>
[color=!@$%^]Lowercase COLOR !@$%^[/color]
