Update 1.1.3: Small fixes

Hey!

Another update -- version 1.1.3, for those keeping count -- is available for download.

Similar to last time, it fixes a few issues:

• Fixed the double-jump trail not disappearing when grabbing ladders or swimming
• Fixed the possibility to backstep in spider-form
• Fixed the music being loud on startup when the volume was set to zero

I also slightly improved the dash by making it go full speed the moment you press the button.

Enjoy! ;)
