The JavaScript for creating the map does not get cached into cache_filter table

The JavaScript for creating the map does not get cached into cache_filter table because it is added to the page by using drupal_set_html_head and drupal_add_js functions. To fix this problem, the JavaScript must be added directly to the filtered text (instead of using drupal_set_html_head and drupal_add_js functions). The patch for this issue can be found in the attachment.
