News Alignment Fix

- Better aligns the *News:* item so it's floating right, maintaining
RTL/LTR compatibility and without messing up multiple-line news items.

Edit Language Description Alignment

- The edit language cat_bar and information description block was pushed
right up against the block below, added 8px bottom margin to separate
the blocks, looks much better this way.
More efficient selector

- The width was being forced on the wrapping anchor block element with
the goal of resizing the image to 40x40px. Now utilizes a "more proper"
selector by forcing the width and height of the actual image element and
also now uses the max- prefix for the very rare scenario of an avatar
being smaller.
