A new talent tree, Convergence!

Chromatic Mastery manages interaction of light + elemental damage.
Invigorate Eyestalks is refigured from the old Tribeam.
Overexposure provides a damage buff that feeds back into Chromatic Mastery.
Tribeam Laser is refigured, again, from the old Tribeam.
... Of these, I plan to merge Overexposure(back) into Tribeam and replace with a shielding talent.
