Bind ~ and ! operators in LSL tighter in order to resolve issues in LSL where these aren't evaluated propertly.

Addresses http://opensimulator.org/mantis/view.php?id=3268
Commitig the Avination implementation of llTeleportAgent and
llTeleportAgentGlobalCoords. These do NOT use PERMISSION_TELEPORT like
their SL counterparts because that permission is not yet understood by TPVs
based on v1.x.

Add last frame time monitor to MonitorModule now that this value is useful
Revert "Bind ~ and ! operators in LSL tighter in order to resolve issues in LSL where these aren't evaluated propertly."

This reverts commit a8a9d13dc07bc9e23ebf439cbea5ece6ae002315.

Accidentally committed, this patch might not be the correct approach.
Set CreateDefaultAvatarEntries = true in Robust.HG.ini.example to match Robust.HG.ini

Thanks to Ai Austin for the spot.
Comment out the scene presence sitting debug log messages for now
In PresenceDetector.OnConnectionClose(), use the IsChildAgent check already available on IClientAPI.SceneAgent rather than retrieving it again by scanning all scenes.
If the simulator closes a root agent due to ack timeout, then send the client a kick message with that reason, in case it is somehow still listening.
Set IClientAPI.IsActive = false early on client removal due to ack timeout rather than using IsLoggingOut flag.

IsActive is more appropriate since unack timeout is not due to voluntary logout.
This is in line with operations such as manual kick that do not set the IsLoggingOut flag.
It's also slightly better race-wise since it reduces the chance of this operation clashing with another reason for client deactivation (e.g. manual kick).
OnConnectionClosed listeners, retrieve data from IClientAPI.SceneAgent rather than scanning all scene for the presence with the right id

Stop checking IsLoggingOut on these listeners, if called with a root agent then we always want to perform these actions.
This covers cases where the client is closed due to manual kick, simulator shutdown, etc.
Remove accidental timeout left in during earlier debugging.  Has been in since two commits ago (b099f26)
Add variable timer configureation for the timer_Script

	Added "timer_Interval" to the OpenSimDefaults.ini, leaving the default value set to 1200, as the previous default setting. The value represents seconds. To change the default, copy the entry to OpenSim.ini and multiply the number of minutes for the interval by 60.
Don't include time to transmit response back to requester when assessing slow handling of requests.

This is to avoid logging a 'slow' request when the source of delay is the viewer in processing a response.
This is not something we can do much about on the server end - it's server-side delay that we're interested in.
To ensure consistency, this commit also had to refactor and simplify inbound non-poll network request handling, though there should be no functional change.
IOSHttpResponse no longer exposes the Send() method, only classes in OpenSim.Framework.Servers.HttpServer should be doing this.
Only the GetTextureHandler was sending its own response.  Now it leaves this to BaseHttpServer, like all other core handlers.

Committing the Avination implementation of llCastRay. This is a complete rewrite
wich does it's thing independently of physics. Enjoy!
Add the updated OpenSimDefaults.ini for the prior timer_Interval patch.

Add "deregister region" by uuid command to grid service to allow manual deregistration of simulators.

Useful if a simulator has crashed without removing its regions and those regions have been reconfigured differently
