Improved volume control

[mdingena]

Changed from linear to logarithmic volume control. You will notice that the silent end of the volume bar is now less sensitive, and the loud end of the volume bar is now more sensitive. This source explains why linear volume control is bad and why logarithmic is awesome: http://dr-lex.be/info-stuff/volumecontrols.html
Make jPlayer more awesome, use this PR.

Thanks for your very cool logarithmic volume control.

Thanks so much mdingena, I've merged but for backwards compatibility reasons we may decide to have an option for logarithmic volume control and have it turned off by default. This is what we usually do for features like this.

That's fine. Happy to contribute! I've been using jPlayer for many years now with a custom skin and my sortable playlists hack #357. Take a look at that PR. It's jQuery specific though and I believe you guys want to go framework independent. But it might be enough to spark your interest or to put it on the roadmap for native jPlayer support.
