Project Kairos Update

[chaosvolt]

I've been meaning to do this for a while but only recently got time and energy to work on this, ever since DDA finally added the stuff utilized in #253 I can also add the intended reward for completing Nicholas' mission chain.

Combining all the research from the missions both Sofia and Nicholas send you after will allow Nicholas to make a device that draws on the energy from portals, much like the restored ritual blade. Its effect when activated is a powerful AoE healing spell affecting the user and any allies in the radius, as well as fixing terrain like Consecrate and having a similiar regrowth effect to the Sacrificial Regrowth spell I helped Foulman write for CleverRaven/Cataclysm-DDA#37254.

BN version:

• Add the item itself to the JSON.
• Add the spell definitions to the JSON.
• Add the spellcasting side effect to JSON, and effects for post-mission dialogue.
• Add the new ter-furn transform used by the spell effects.
• Edit missiondef for Nicholas' final mission to add required post-mission effects.
• Add achievement for obtaining the item from Nicholas.
• Edit Nicholas' dialogue to allow speaking to him and obtaining the relevant item after a given amount of time.

DDA version:

• Add the item itself to the JSON. Will need pocket data added and use DDA-specific hackery to work around lack of ARTC_PORTAL.
• Add the spell definitions to the JSON, adding extraneous blast spell shapes where needed.
• Add the spellcasting side effect to JSON, and effects for post-mission dialogue. Permanent boolean needs to be removed where needed.
• Add the new ter-furn transform used by the spell effects.
• Edit missiondef for Nicholas' final mission to add required post-mission effects.
• Add achievement for obtaining the item from Nicholas, syntax will be different for DDA version.
• Edit Nicholas' dialogue to allow speaking to him and obtaining the relevant item after a given amount of time.

All that should be left now is follow-up testing of stuff.
