fixed: base_url_redirect config option was not read from the config file

and was not used when checking for base url redirect
fixed: return values from plugins should be given in a special structure
       they were remembered in plugin object (ret_false, ret_true)
       and consequently were not thread safe
       now all plugin.Call() methods return PluginRes structure 
       in which there are ret_false and ret_true variables       
changed: small refactoring in AddUser winix function
