Made it so the Black Flame Grenade can be built instantly if you have the Bomb Squad resistance order

Apparently the Xcom Black Flame Grenade was not properly applying the status effects when launched with a Grenade Launcher, should be fixed now.

Quick update to fix some issues with the Devastator's Lightning Vengeance ability(their revenge melee counter ability), the ability should still activate if the Devastator is on fire, disoriented, or confused. But not if it's frozen, stunned, bound, or stunned.

Black Flame Grenade should now have localization when launched with a Grenade Launcher.
Black Flame Grenade Autopsy should now properly proc instant research(apparently the instant thing only procs when you finish a different research, the more you know).
Black Flame Grenade shouldn't be buildable in the Engineering bay anymore.

The Muton Harrier's weapon should now work properly, before it would deal damage to targets in an AoE around the primary target, but never deal damage to the primary target. It should now be capable of dealing damage to everyone in the AoE. Note that despite technically being grenades, they can still miss.

[Cosmetic changes]
Improved the particle effect of the Beleaguer's projectile.
Added some slight spread to the Harrier's grenade projectile.

Updated to fix the localization issue with the new status effects. Thanks to Mitzruti, and RustyDios.
Also added research tech stuff to the X2DownloadableContentInfo.UC to hopefully make the research show up in existing campaigns.
