Feature request about 3DSounds

[thisnickwasfree]

I see the 3DSound section is WIP. So, here is a feature request. Could you make a sound pool? For example, we need to play one sound several times: ten explosions, for example, or footsteps while mob walking. So, starting new sound, we are checking it's playing status, and if the sound is playing, we create a copy of it;s source and starting to play it. The creation of new copies can be limited: if we are out of limit, we stops first sound in pool, and starts it again from initial position.
