Removed errant property condition that interfered with checking if a unit was unconscious. (Unit HP gets weird when they're knocked out, as it turns out.)

Fixed visual bug preventing units from properly getting back up after being revived. They still worked before, but it meant Axiom was shooting from the ground lying on the floor.

Re-reading the source code made me realize Firaxis changed their minds about using Downed for XCOM instead of Unconscious, so now Revive actually removes the actual effect preventing your soldiers from getting back up.

Added check so it doesn't proc off *hostile* downed units.

Also readjusted the downed condition check so it's on the ability itself and just not on the effects of the ability. This way targeting should be properly affected.

Revive should now only want units that are actually downed, now.
