Revert "Save the Telehub and its Spawn Points in the OAR"

This reverts commit b0b7b45b943dd94546bcfcf5d3bb871cfe35b507.

Sorry BlueWall, I wanted to discuss an aspect of the data storage but I couldn't assign bugs in 'patch included' state to myself until I changed mantis just now and I forgot to mention it on irc.
I wouldn't normally revert but thinks get tricky when it comes to data formats.
Essentially, I would like to see the Yaw, Pitch and Distance values as separate XML entities (as used in other aspects such as vectors, quaternions) rather than as a . delimited string
We can discuss this more with Oren in opensimulator.org/mantis/view.php?id=6008
Fix mono compiler warning.

Last jenkins failure looked like a glitch.
Fix indexer to spawnpoints
Formatting fix
Add configurable SpawnPointRouting

	Will use one of three selected methods to route avatar landing
	points when using Telehubs. The setting is in [Startup] using
        SpawnPointRouting = closest/random/sequence

	closest: The default setting. Routes avatar to the nearest SpawnPoint
	to the location.

	random: Picks random SpawnPoints to land the avatar.

	sequence: Follows a sequence to place the avatar on the next available
	SpawnPoint location

Modifications for SMTP in OpenSimulator. Email size limit was fixed (was out of step with documentation at 1024, so boosted to 4096). Added configuration item for maximum email size. Redundant sleep inside email module was fixed (LSL Api was already sleeping). Added sleep time configuration item for snooze between email sending for LSL Api. Added two new configuration items (email_max_size and email_pause_time) into the example OpenSim.ini, plus fixed a spelling error (llimits) and odd tabbing.

Set the agent in transit teleport flag at the first available opportunity (i.e. when IsInTransit() was being checked) to close down a race condition.

On EntityTransferModule.DoTeleport() there was an IsInTransit() check to prevent multiple simultaneous teleport attempts.
However, the SetInTransit() was only performed later on, which left a window in which multiple threads could pass the IsInTransit() check.
This has been seen in the field and the results aren't pretty.
This commit effectively combines the IsInTransit() and SetInTransit() checks so there is no such window.
More failure cases are made to to call ResetInTransit() to adjust to this move.
minor: comment out individual attachment transfer log messages for now
minor: add explanative comment to 'missing baked texture' logging commonly seen on inter-simulator teleports where avatar baked textures are not available from the asset service.
