Rework council keleres UI and how its counted + Wormhole bugfix

[shenanigans-be]

This should fix

• Can't create draft with all 30 factions #99
• Number of races limited to 17 with Prophercy of Kings (should be 24) #106
• 'Include Council of Keleres' does not work without 'Expansion to use: Thunder's Edge' activated #104
  in one fell swoop.

Council Keleres is.. annoyingly exceptional. I figured I could get away with leaving it as is, but I'll be damned if people don't notice the small stuff 😅

Fixes include:

• Thunder's Edge now counts 6 factions instead of 5.
• The checkbox to include council keleres is always checked when TE is included.
• Council keleres adds +1 to max factions when POK is included, but TE is not
• Also fix "Include Wormholes" button no longer working. #105 while I'm at it
