Add support for misc mods in Uniques and Tree

[Blitz54]

EDIT: Check both comments plz

Description of the problem being solved:

The passive tree had multiple nodes for "%Increased/Reduced Projectile Speed for Spell Skills", at the top right of the tree, notables being "Turn the Clock Forward" and "Turn the Clock Back". While adding the Chance of 2 Add Projs, I realized the quality on Fireball also adds chance of 2 projs, so that seems to calculate too now.

The same cluster as well as another south west of it, had "% chance for Spell Skills to fire 2 additional Projectiles"

I figured a separate text box for the 2 additional projectile chance was a better option than tacking on fractions of a projectile to the projectile count. I decided on "2 Add. Proj. Chance" for the short description, although suggestions appreciated. I avoided using +2 because I feel that would cause confusion with +2 skills. The other names in the code like "TwoAdditionalProjectilesChance" feel long but necessary, as it's not just a chance of ONE, but two projs. So if GGG adds any mods that give a chance of one additional proj, it would have to be implemented separately.

Steps taken to verify a working solution:

-Tried to copy previous implementation of "Terrain Chain" to keep everything uniform.
-Added a spell flag to the % chance 2 proj, so that it doesn't apply to bow skills like snipe or LA.
-Tested ball lighting and ember fusilade in game to confirm it does apply to the skill. They work, and I'm assuming GGG has been consistent with this.

Ended up finding a bunch of other surface level stuff I could tackle.

• Blind chance shown in "Other effects" in calc.
• +1 grenade projectile from "Cluster Bombs"
• +2 chain from "Mist Whisper" unique crossbow
• cannot be chilled or frozen from "Dream Fragments"
• "Long Fuse" support 30% more damage
• "increased effect of auras from your aura skills"
• "reduced effect of ignite on you"
• "duration of ignite, shock and chill on enemies"
• "damage penetrates 10% of lightning resistance if on low mana" Jacked the bosses resistance super high and it does affect the dps when I set low mana, is there anywhere that shows total elemental penetration?

Think that's all, or very close. Let me know if there's anything I could do better.

Would be good to integrate this into the main projectile count box instead of being separate as we use the projectile count of a skill in a number of areas for DPS calculations

I made a couple fixes to your PR before merging

[Blitz54]

@LocalIdentity coming back to this line. BlindImmune is used for the CalcSections page for "Blind Avoidance Chance".

PathOfBuilding-PoE2/src/Modules/CalcSections.lua

Line 1774 in 278ccf8

{ label = "Blind Avoid Ch.", haveOutput = "BlindAvoidChance", { format = "{0:output:BlindAvoidChance}%", { modName = { "AvoidBlind", "BlindImmune" } }, }, },

And in CalcDefence.lua,

PathOfBuilding-PoE2/src/Modules/CalcDefence.lua

Line 1615 in 278ccf8

output.BlindAvoidChance = modDB:Flag(nil, "BlindImmune") and 100 or m_min(modDB:Sum("BASE", nil, "AvoidBlind"), 100)

although I'm not sure on how it's used there exactly. Any specific reason why there is 2 flags like that? Is it possible/worth it to combine into one flag?

Also, CalcPerform.lua uses CannotBeBlinded, but doesn't seem to prevent blind on line 505.

PathOfBuilding-PoE2/src/Modules/CalcPerform.lua

Line 505 in 278ccf8

if modDB:Flag(nil, "Blind") and not modDB:Flag(nil, "CannotBeBlinded") then

Toggling "are you blinded" is config lowers evasions by the 20%, or equipping and item with "you are blinded" also bypasses the check. I assume CannotBeBlinded should be priority right?
Adding Condition:CannotBeBlinded seems to make it function properly.
