Default COMMITTED: Tribute Focus, SE_DivineSave, SE_Flurry, SE_Accuracy

Sorry for posting all of these together, but for the most part they are all related changes. I may over-explain some of this, especially to the devs who already know what this stuff is anyways, but I want it to be very clear what this is implementing.

The main change is adding the active tribute inventory slots to the Client::GetFocusEffect routine. All tribute focuses should now be working. (Actually, I think ALL personal tribute is now working)

The rest of the changes came about while working on tribute.
The tributes "Fury of Combat" (SE_Flurry), "Eyes of the Hunter" (SE_Accuracy) and "Second Chance" (SE_DivineSave), are now implemented.

"Fury of Combat" is actually misdescribed in the tribute window, it is not a higher chance to double attack, but a chance to flurry (chance per round to execute 2 extra attacks). For reference see spell 5608 from tribute item Benefit: Flurry 03.
The spell effect is 279 (SE_Flurry). I can provide forum posts confirming this is flurry on live if needed (and mislabeled on live too).

"Second Chance" is a Divine Save. This is not Death Save, but is very similar. The spell Divine Intervention provides a Death Save, when your hp hits 0, it is simply a chance for a full heal, and then it's gone.
A Divine Save happens when your hp hits 0 as well, but if it activates, you are given the buff Touch of the Divine, with a HoT and invulnerability for 6 tics. I have added code to force the duration to ignore focus/AA extensions.
I don't know if it gets extended or not on live.

Some notes on the Accuracy code. Accuracy = HitChance, except it affects all skills automatically. Hit chance always either specifies a specific skill or All Skills.

Itembonus Accuracy and HitChance don't stack with each other, it will choose whichever is higher (but won't choose HitChance if it's higher but for the wrong skill).
The same goes for Spellbonus Accuracy and HitChance. However, the results from Itembonus and Spellbonus do combine. This is an assumption based on how other things work, I don't really have any live data to work with on it.

Like the current HitChance implementation, a negative Accuracy mod doesn't work. I modelled Accuracy based on HitChance (as it is effectively the same), and it was already noted in the source that something needs to be reworked to allow for that.
I think this should still be added for the time being, and someone needs to think about how to work this problem out. I plan to take a look at it, but it may be beyond me.

As for the Flurry implementation, any class is able to buy the flurry tribute, so I let it activate for any class. If an enchanter is meleeing with the flurry tribute at rank 3, they should get an extra 2 attacks per round 6% of the time, etc.
I don't think thats a big deal. From reading around, it seems like a lot of people think a flurry can only happen on a successful triple attack. I don't know how it really works, but in the current revision 1639,
it works fine without a triple attack and gets a bonus on a successful one with the right AAs. Obviously only a few classes can triple, but all classes can buy this tribute... so I guess this implementation should be fine.

This diff adds the 3 new spell effects, adds the tribute focus fix, and changes Mob::TryDeathSave() to account for the SE_DivineSave from tribute/other spells.

This diff adds the variables to Mob to support the new spell effects. It also exposes the mob buff_struct so I could get a buff property in my #showstatbonuses command above.
A specific slot buff would be accessed as GetBuffs()[slot] .. maybe not the prettiest hack.
If you don't implement that command you can take out that line from here, if you want.

I have tested all of these changes, mostly through in-game debug #logs/#mlog etc, hitting things, changing things... hitting more things. Killing myself 70+ times testing the divine save (and death save).
Killing a mob a rediculous number of times with Divine Intervention cast on it. Fun stuff. I've spent hours making sure this works as intended.

If anything is implemented wrong, let me know and I'll correct it.

Sorry for writing a book here. I hope this is formatted well enough for you.

Thanks for this. I've committed it, but I only really tested the Tribute part of it.

Sorry for the ten year thread necro, but I have used search and advanced search to no avail. Given the community movement towards UF and RoF1+2, what is the top level as of 2020 for personal tribute offerings?

I am not finding gear upgrades to many of the staple spell focus benefits like affliction haste IV, V, + or burning affliction IV, V, + on a new server with numerous updates and high level zones available... the level limit is 70 but the LDoN and Tribute selections are apparently stuck at level 65.

What to suggest to the server op? Any help welcome and appreciated (and sorry, no, I was a GM for a "Wrath Era" WoW server, not a past or present EQ1 server).

Thanks!
