Suggested changes to Widget CSS, display:block issues on links

[onefinejay]

Display:block on A is nice for hover states but play havoc on widgets that have post counts, as well as recent comments: https://gist.github.com/onefinejay/d2659339b2cc4b559e31

It duplicates the look of .widget li a, but on the parent li elements. Hover states included, too.

.widget.widget_archives and .widget.widget_categories broken out in case someone wants to change their layout accordingly. Consolidate as needed.
