* Removes the left padding on the first cell in a row, and the right padding on the last cell in each row - the padding is still there between cells, so the contents don't meet.
* Does the opposite for RTL, and fixes some spacing issues.
* Updates the editor styles to match.

* Fixes the display issues with the header. The header doesn't look exactly like it does in newer browsers, but it's closer.
* Gets the font sizes a bit more consistent with how it looks like other browsers.
* IE8 doesn't support SVGs, so it's using the fallback styles for some of the icons. The fallbacks are limited to the absolutely necessary icons - so there is one for the submenu dropdown toggle icon, but not for the little 'hamburger' and X that sit in front of the 'menu' button.

Currently, it's hard to output an SVG in the comment function without a lot of extra effort. So this adds a simple border to the author avatar and removes previous code related to SVGs and/or Genericons.
