apWebServicePlugin can't save UserAgent string to connection DB

If user logged by apWebServicePlugin, the user agent string won't stored to Statistics.

We need change this file

apWebServicePlugin/lib/model/apWS_v1.php auth.palmstamp.net/plugins/apWebServicePlugin/lib/model/apWS_v1.php

at line 229, add this line to get user agent string for connection:

 $connection->setUserAgent($_SERVER['HTTP_USER_AGENT']);
