Delay SINGULARITY_GEN, reduce ART_BLACK_HOLE build time

[Oberlus]

Makes Singularity Generation tech require Temporal Mechanics and reduces build time or Artificial Black Hole (from 10 to 6), so that empires with a nearby Black Hole with planets doesn't have a great advantage over empires that must research Artificial Black Hole.

Much preferably.
Not having it is not gamebreaking in single player. It's mostly intended to level gameplay in multiplayer.
