Codex: Chaos Space Marines

Shared profile links and entry: Khorne Bezerkers-Warp Talons (leaving
Warpsmith and Thousand Sons of base codex entries to modify)

Added Forgeworld, Battle Formation and Formation to the entries which
were any one of those three types.

Altered the Chaos Lord and Sorcerer entries to have their weapon
selection options separate to the armour (for easier use on mobile
devices). Armour selection will determine visibility of the weapon
options in these two units.  Closes #435
