1.10.0 API changes (Iriel)

Here's my collection of the API changes for 1.10, based on the 0.10.0-5195 test realm build. As always it's expected that you read this thread in conjunction with the rest of this thread.

"Gotchas"

 * GameTooltip objects will not work unless they've had an owner set. Try :SetOwner(WorldFrame,"ANCHOR_NONE"). Also avoid giving them parents, when the tooltip or its parent is hidden, it will not work properly, and when shown again you must re-SetOwner it.
 * RegisterForSave can no longer be called from non-Blizzard code.
 * There's a new SPELLCAST_CHANNEL_STOP event which replaces both the final SPELLCAST_CHANNEL_UPDATE (arg1==0) and SPELLCAST_STOP for channeled spells (Thanks for Miravlix for researching this).

Widget API Changes (INCOMPLETE!)
All UI Objects have the following NEW methods
 * objType = LayoutFrame:GetObjectType - Return the object type for this object (Similar to Frame:GetFrameType but supports all UI object types)
