function feeds_tamper_form_feeds_ui_mapping_form_alter in Feeds Tamper 6

Implementation of hook_form_feeds_ui_mapping_form_alter().

This is an interesting bit of work. Each source name has to be unique, but we have no idea how many to create with feeds_tamper_feeds_parser_sources_alter() because we don't know how many targets there are going to be.

The solution is to keep track in the form how many have been added.

function feeds_tamper_form_feeds_ui_mapping_form_alter(&$form, &$form_state) {

  // Don't alter the form for parsers that use manual input.

    return;
  }
  $newest_source = NULL;
  foreach ($form['#mappings'] as $mapping) {
    if (strpos($mapping['source'], 'Blank source ') === 0) {
      $newest_source = $mapping['source'];
    }

    list(, , $count) = explode(' ', $newest_source);
