Little patch for query string in swf filename

Hello, there is a small bug in the swftools.module, if the filename has a query string, the swftools_get_action function will not return the good action because of the file's extension.

To correct this bug, replace in swftools.module at line 642 :

function swftools_get_action($file) {

by :

function swftools_get_action($file) {
  // If query string, get it's position
  if (($q = strpos($file, '?')) !== FALSE) {
    $file = substr($file, 0, $q);
  }

And use the stream variable in othervars when you call swf else the filename will be reset.
