Sync update.

Version 4.7a

-Additional improvements to treemen sounds.

Version 4.7

-Increased the attenuation of the deck cannons.
-Fixed the treemen's abruptly ending screams.
-Minor changes to various sound levels.

Version 4.6

-Significantly improved melee sounds by making "impacts" louder. Also promoted melee, impact and collision sounds so that they are "larger" (have a higher priority) and less likely to get dropped or cut out when more than 500 sounds are being buffered.
-Various small adjustment to sound levels.

Version 4.5a

-Corrected a typo (from the previous update) in the attenuation level of the (unit) group sounds, which caused melee sounds to be too quiet.

Version 4.5 (revised)

(After 45 versions, finally made a breakthrough trying to unravel the mess that is the melee sounds. It took a LOT of work to get here.)

-Made significant adjustments to melee group sound behavior, to address most of the "silent melee" problems. Melee sound may still drop out from time to time, and there is probably only so much of this that can be addressed, but overall sound behavior should be much improved over the standard game now.
-Re-introduced back some melee vocals for select units where it makes sense.
-Many fine adjustments to volume of Foley and vocals.

Version 4.4a

-Various small improvements to vocal levels of large monsters.

Version 4.4

-Significantly improved melee sounds by locating what seems to have been the problem all along. Several melee impact sounds had been given such a low probability (of playing) that it caused there to be silence. The assumption here is that the melee sounds combined with the blasting vocals were too overwhelming so CA (poorly) chose to restrict the melee sounds.
-Now melee impacts against armor, shields and weapons are heard all the time, rather than rarely.
