changing poster image to div with backgroundImage

The existing poster implementation uses an <img> tag
stretched horizontally with capped max-height. This
works in some cases like pillar-boxing when the poster
is not as wide as the player. However it fails to
letter box when the player is taller than the poster.

This change uses a stretched div with background-image
and backround-size to create a vertically aligned
poster image which stretches in both directions to fit
while maintaining aspect ratio.

For browsers which do not support backgroundSize (IE8)
the original <img> based strategy is used as a fallback.
Fix 347
Hide volume slider and mute toggle when the current tech doesn't support adjusting video volume. Added controls specific test cases. Volume-related controls retest whether to display themselves whenever `loadstart` fires.

Reformat `var` statements
Declare them in a single line at the top of the function and initialize them later.
Block defineSetter test for older IE
__defineSetter__ doesn't work on some versions of IE, so just ignore the volume/mute toggle tests when run on those browsers.
Remove phantom UA check
The volume controls and mute toggle are guarding against not having a tech present, so it's no longer necessary to mock the tech for all command-line tests. Individual tests continue to do so using PlayerTest.makePlayer.
