Enhance media controls

[jooola]

Just completed and reworked the controls bar.

• added reapet/shuffle button
• added playing progress bar
• better css for input type=range

Some clean /fixes

Need some work to get it really cross-browser compatible (appearance)

@bfkelsey Will you have time to review those PR or you don't have time for this ?

I'm willing to build quality features so if you see any ugly parts would you tell me ?

Sorry I am pretty busy these days. Looks pretty good besides that one small fix.
