Buff the Incenses in the Incense Crucible

[srdr2k3]

This PR aims to buff the incenses used in the crucible to make them available earlier and make them more powerful.
Also includes a minor tweak to the great-self sacrifice mechanic.
Feel free to tweak numbers.

First of all, incenses:
Wood Ash (Yellow): LP multiplier increased from 1.3 to 1.4.
Byrrus (Red): 1.6 -> 1.8, recipe shifted from apprentice orb to weak orb.
Livens (Blue): 2.2 -> 2.5, recipe shifted from magician orb to apprentice orb.
Viridis (Green): 3 -> 3.4, recipe shifted from master orb to apprentice orb, uses blank slates in the recipe to give more of a cost for the benefit it gives.
Purpura (Purple): 4 -> 4.5, recipe shifted from archmage to master orb, uses reinforced slates in the recipe for the same reason above.

All of the incenses have also been doubled in the duration it takes to completely use one in the crucible. (50s -> 100s)

I've also lowered the duration of the Soul Fray debuff when you use the great-self sacrifice. (20s -> 12s)
My reasoning for that is that the incenses take a while to charge up anyway.

This seems like a nice buff to an underused mechanic, thanks!
