Combine and Zombine flatlines (death sounds)

Preview here. What this does: When a combine soldier or zombine dies, it now flatlines like a CP officer or the soldiers from Half-Life: Alyx. The zombine's sound effect is more "broken" and gross sounding. Zombine will not flatline 1/3 of the time, as their third death sound is a reused noise from standard zombies. I do have a flatline version of that sound, but the method I use to implement it doesn't work outside of an SDK Base 2013 mod... sorry. The radio click when a regular soldier dies is the HL2 walkie talkie, which may sound out-of-place in the episodes, so your mileage may vary. A zombine would logically flatline, as... The headcrab must keep blood flowing for the body to be ambulatory (note the green veins on the HL1 zombies!) A zombine's posthuman augments are still semi-operational
