Add explosive fizzle sound

[braem]

Closes #1048

Adds explosive fizzle sounds to CMomExplosive's. Default sound is on the quiet end and is just a placeholder for when we make a custom sound.

Adds a Fizzle() virtual function to CMomExplosive and removed the field from Destroy. Fizzle destroys the explosive, then plays the fizzle sprite and sound.
Fizzle sounds for specific weapons are easy to add; just override GetFizzleSound() with the sound script.

Also cleans up the stickybomb launcher and stickybomb code:

• Removes the bFizzle field from DetonateRemoteStickybombs in the launcher. Fizzling code is mostly in the stickybomb and this function was never called with this field as true.
• Removes m_bFizzle in the stickybomb code. Seems like this was used to interface with DetonateRemoteStickybombs and has been superseded by m_bCanExplode.
