Poll tpls and markup converted to valid HTML5

Added
function theme_meter($variables) was added to allow for theming of progress meters in the poll module.

You can edit the following attributes:

• display_value: The textual representation of the meter bar.
• form: A string specifying one or more forms to which the element belongs separated by spaces.
• high: A number specifying the range that is considered to be a high value.
• low: A number specifying the range that is considered to be a low value.
• max: A number specifying the maximum value of the range.
• min: A number specifying the minimum value of the range.
• optimum: A number specifying what value is the optimal value for the gauge.
• value: A number specifying the current value of the gauge.
• percentage: A number specifying the current percentage of the gauge.
• attributes: Associative array of attributes to be placed in the meter tag.

This function was initially designed for the <meter> tag, but due to the lack of browser and styling support for it, we're currently using it's attributes as HTML5 data attributes on a <div>.

All variables except display_value, percentage, and attributes can be added to an array to replace default class attributes.

percentage determines the width of the child div.
display_value is placed in a div class percent for displaying numerical results.

Below is an example theme function that can be used to take advantage of the meter tag:

function mytheme_meter($variables) {
  $attributes = $variables['attributes'];

  foreach (array('form', 'high', 'low', 'max', 'min', 'optimum', 'value') as $attrib) {
    if (!is_null($variables[$attrib])) {
      $attributes[$attrib] = $variables[$attrib];
    }
  }

  $output = '<meter' . drupal_attributes($attributes) . '>' . $variables['display_value'] . '</meter>';

  return $output;
}
