Subject: Mantis#852. Thank you kindly, cmickeyb for a patch that: There
 appears to be a problem with the mapping of scripts when an llHTTPRequest
 completes. CheckHttpRequests() looks for a function that maps to the localID
 associated with the http request. However, the only context in which it looks
 is that of the first region. That is,
 m_CmdManager.m_ScriptEngine.m_ScriptManager is the same no matter where the
 script executed that initiated the llHTTPRequest. Since scripts appear to be
 loaded into a region specific scriptmanager on startup, the event handler is
 only found for requests coming from the first region.
