Subject: Merging from the server/server-1.25 branch

svn merge -r107352:108210
svn+ssh://svn.lindenlab.com/svn/linden/branches/server/server-1.25

Merge conflicts were resolved:

  scripts/start-server   : one conflict, kept the "working" version

  indra/llcommon/llversionserver.h : reverted
  indra/newview/Info-SecondLife.plist : reverted
  indra/newview/res/viewerRes.rc : reverted

  indra/newsim/llagentinfo.cpp : kept *both*... "working" had
      is_agent_online, which nothing else had, and the merge had
      isGodAllowed(), part of SEC resolution

  indra/backbone/agent_router.py : kartic & rdw merged and reviewed
      using brains and things

  indra/newsim/llsimhttpresponder.cpp : doesn't exist in trunk, and
      that's OK (even though there was a change for it)
