German Martinshorn (Pressluft) 2297GM 1.0.0

Due to a suggestion of @NoMore112 , I created this little modification.
It features the "traditional" german compressed air hi-lo siren.

Demo Video:

Installation (You need OpenIV):
1. Go to mods\x64\audio\sfx\RESIDENT.rpf\
2. Right-click vehicles.awc and choose "export to Open Formats (.OFT)."
3. In your new vehicles folder you have to drag and drop the wav-files from the archive and replace the old ones.
4. Now click on new and choose "import Open Formats file."
5. Choose your vehicles.oac. When it has been imported you're done!

I really recommend you to use it along with my siren pack (install it first then).

It would be awesome, iwhen you could leave a comment or a rating.
I'll also contemplate requests, if you have any.
Thank you! :D
