Reduces the formats of fonts that we're including in the player. Since IE8 is dropped, we're removing EOT fonts as IE9 supports WOFF. IE9 in compatibility mode would need EOT fonts, but the player is not functional in compatibility mode there is no point in including them. WOFF and TTF alone should be sufficient to cover all necessary circumstances. Removes the @import "../imports/icons" from six since it's causing the broken fonts on the test pages. It attempts to load fonts which do not exist and the request fails before the browser has finishes decoding the base64 encoded fonts. This causes the browser to assume the font is broken so it displays character codes instead. The font afterwords finishes decoding and displays correctly. Adding the only bit needed from @import "../imports/icons" to the six skin. [Finishes #99324726]
Modified play and complete icons to be more visually centered in the icon. They're not placed directly in the center of the icon anymore, which could look odd if icons are stacked next to one another without padding, but this is not a use case we have in the player at the moment.
Sets the display icon width and height to be equal in the core skin (3.5em) and removed padding-based centering. centering now done via text-align. Slight bump to the right in the idle mode of the player and slight bump upward on complete mode so that the icon looks a bit more visually centered in its container. [Finishes #98200440]
