ModIntegrity 2.0.0 doesn't recognize SWAP_WEAPONS ability requiring 2 projectile types

[AlyMar1994]

After an integrity check on UFoCP, this came up:
Data\XML\Units\UND\Units_Hero_Underworld_Bossk.xml:66: unknown game object "Proj_Hand_Blaster_Bossk, Proj_Bossk_Plasma_Grenade".

These two projectile types are valid, and so is the syntax. The ability works fine in-game, but the tool marks it as an error.

Tested on FoC, line 600.
