Significant Changes

* The blizzard UI is being converted to use 'self' and the other local arguments in favor of 'this' and argN. 
  The old style arguments are going to be obsoleted, so AddOn code needs to be updated too.
  This may mean there are changes in the signatures of Blizzard UI functions - update code that hooks or replaces the blizzard UI where necessary as well. !!!

* UPDATED: In the current beta build slash command handlers have a new 'self' parameter before the message that is the edit box the command ran from.
  As this is a cause of major backward incompatibility the change is going to be reversed and the editBox will come AFTER the message -- ETA unknown !!!

* The SecureStateHeader has been replaced by a new secure template which allows for a more natural specification of rules in lua rather than via complex state tables.
  More details will be forthcoming. !!!


Buff Information
* The various GetPlayerBuff functions have been removed and integrated into the appropriate unit functions, adding a new UnitAura function and updating the others:

name, rank, texture, count, debuffType, duration, timeLeft, untilCanceled = UnitAura("unit", [index] or ["name", "rank"][, "filter"]);
name, rank, texture, count, debuffType, duration, timeLeft, untilCanceled = UnitBuff("unit", [index] or ["name", "rank"][, "filter"]);
name, rank, texture, count, debuffType, duration, timeLeft, untilCanceled = UnitDebuff("unit", [index] or ["name", "rank"][, "filter"]);
CancelPlayerBuff([index] or ["name", "rank"][, "filter"]);

GameTooltip:SetUnitAura("unit", [index] or ["name", "rank"][, "filter"]);
GameTooltip:SetUnitBuff("unit", [index] or ["name", "rank"][, "filter"]);
GameTooltip:SetUnitDebuff("unit", [index] or ["name", "rank"][, "filter"]);

* The "filter" parameter can be any of "HELPFUL", "HARMFUL", "RAID", "CANCELABLE", "NOT_CANCELABLE". You can also specify several filters separated by a | character to chain multiple filters together (e.g. "HELPFUL|RAID" == helpful buffs that you can cast on your raid). By default UnitAura has "HELPFUL" as an implicit filter - you cannot get back BOTH helpful and harmful at the same time. Neither "HELPFUL" or "HARMFUL" have meaning for UnitBuff/UnitDebuff, and will be ignored.
* AddOns displaying remaining time should cache the time left and decrement their own counter, do not re-query the information every OnUpdate.
* The untilCanceled return value is true if the buff doesn't have its own duration (e.g. stealth)
