New Hydra pack by A_De

Description
New skins for HYDRA slot. Uses TRLE sounds. Pack contains 3 versions of Hydra: green, black and yellow. There are also 2 static versions.

Note
The HYDRA slot parameters are mostly hardcoded, it's animations and mesh structure should not be modified, otherwise the missiles go to wrong directions and also the small fire won't fit hydra's mouth.
