Allow modders to choose what happens to parasites if the host heals

[Black Temple Gaurdian]

Currently, if an infected unit is healed, the parasite is removed. This isn't wanted in certain cases e.g. mind-control parasites, healing parasites...

Can't healing parasites be done the same way as mechanics - positive damage, negative verses?
As for MC parasites, I'm pretty sure they don't get removed at all, since they're not really parasiting the unit.

[Black Temple Gaurdian (black-temple-gaurdian)]

Tried both ways it the heain parasite, it would "infect" the unit but only for the first time. I don't know but I think the problm is it heals the unit, and so desroys itself. MC parasites, I didn't actually test but since it attacks like any other parasite, I'd assume it infectslike any other parasites.

I have tested MC parasite as far as sonic/repair ifv/repair depot goes and none of these remove the parasite
