Fix: shared-host respawn block and web login brand placeholder

Two unrelated fixes bundled here.

1. Client respawn (ClientDll.cpp EasyRun/Run, test.cpp Run): after a host
   is shared or transferred to another server, restarting the master
   (server A) left the host's main instance stuck, because the respawn
   loop waited on IsStoped() (g_bThreadExit && GetCount()==0), which never
   becomes true while a still-alive shared instance holds AddCount(1).
   S_SERVER_EXIT now triggers an immediate reconnect without waiting for
   shared instances; client-exit / update still waits for all instances to
   drain. Verified by 100 restart cycles.

2. Web login page (WebService.cpp): the MFC web server only substituted
   __BASE_PATH__ in index.html and left __BRAND_NAME__ as a literal token
   in the login page title/heading. Substitute it with "SimpleRemoter" to
   match the original branding and the Go server's default.
