Mark VI Drill Grenade ignoring obstacles

[abel1502]

Mark VI Drill Grenade in its current state, effectively, cannot be protected against, as it continues blasting in its line, ignoring walls of reinforced blocks in its way. It will, for example, destroy the contents of a bunker in its way without breaching the structure. I'm not complaining about overpoweredness (that's what the mod's about), but this seems more like an improper calcultion issue, rather than a feature.
Probably low priority. Treat it as a request, I guess.
