Tide no longer affects friendly units

Incresed soul-blade & astral bullet additional damage

Fixed a bug where stance-changes were being granted from reaction fire shots erroneously.

Increased ability points per level up to 6

Fixed an issue with the 'night watchman' ability, which wasn't applying the negation of the overwatch penalty properly.

Added images for GTS perks, adjusted promotion icons to use the same as the psi operative & made a couple of minor ability tweaks.

Actually fixed it this time :D

Fix for reflective barrier exhausting on miss

Update to reflective barrier:

• Can no longer return fire if the warden was stunned / dazed / rendered unconscious / set on fire / panicked by the attacking unit. The shield will still be exhausted even if fire is not returned due to impairment.
  
• Now protects against non-environemtal AOE attacks as well but can only return fire against non-explosive AOE (e.g. faceless claws). The shield will still be exhausted even if fire is not returned.
  
• Environmental explosives which go through the shield will not exhaust it
  
• Cooldown reduced to 3 turns and the number of protected attacks has been reduced to 1.
  
• Fixed a typo in unfavoured classes for bonds.

Initial release, enjoy!
