A small patch for 0.17 taking care of a few issues and stability!

• Fixed a rare crash caused by the crash fix from 0.17 ([b][i]wait the crashes have crashes now?[/i][/b])
• Fixed an issue causing unreliable attack drag calculation
• Fixed a debug element being visible
• Fixed the new rock sound being agnostic of volume setting
• Added changelog to main menu (oops, forgot!)

Here's another gif of some of the new gear in v0.17!
