WSM WSDL fails if password has special characters

[dansmith65]

The password I defined in the Web Services Manager.fmp12 file's Operations > Edit Auth Info area contained special characters (like brackets). The FileMaker file worked fine with this password, but the wsdl failed to load in the browser saying it was unauthorized. This is likely because the password needs to be urlencoded in websvcmgr.php line 1217:

$userPass .= ':' . $pass . "@";
