[bug] Targeting a boss in Raid errors on secret for UnitGUID

[lolswirl]

UnitGUID returns secret values inside of instances, regardless of combat, and is unable to index the table on its GUID for choosing a boss-specific loadout.

Specifically, checkUnitTimeout fails but will later fail if removed from figuring out the type of Unit (and its npcID) from its GUID because of string manipulation

Unfortunately, removed the targeting of a boss to select a new loadout in 3.1 since I can't quite figure out a way to make this work.

Secret value cannot be used for any comparisons, and thus checking if a saved encounterId is the same as the npcId (from UnitGUID) is impossible. UnitName is also secret, so checking for that is off the table. I've tried to implement a SetAlphaFromBoolean check on the frame, but a bool check is still required and requires a comparison of some sort to even get the bool value to pass in, as the name or some form of id is required.

Keeping this open for visibility, but I am at a loss for how to implement this.

Added manually choosing a boss on selecting a boss-unit as target, but disabled by default in 3.4. Still holding out -some- form of hope for automatic detection.
