function panels_ajax_tab_boot in Panels Ajax Tabs 7

Implements hook_boot().

IF Clean-URLs are enabled for any ajax-tab pane, we strip the URL identifier off the end of the URL and place it in $_GET['panels_ajax_tab_trigger']. We additionally put the mini-panel this corresponds to in $_GET['panels_ajax_tab_tab']. Once this is done drupal can handle the URL normally (it won't get confused by the identifier on the end of the URL) and panels-ajax-tabs will look for what tab to load by inspecting $_GET['panels_ajax_tab_tab']. In Essense, it transforms a url like http://example.com/path/to/drupal/page.mytab to a url like http://example.com/path/to/drupal/page?panels_ajax_tab_trigger=mytab&pan....
