Line up elements on themes.php. Line up 'Available Themes' header and search/feature form. Switch to padding instead of margin for #current-theme to prevent margin-uncollapse jitters when animating the feature filter. Move 'Current Theme' inside #current-theme so it is hidden by the feature filter. see #20147.

In miscellaneous publishing actions, use :last-child instead of a separate misc-pub-section-last class to control borders. Allows for sane use of the post_submitbox_misc_actions hook. (Actually uses :first-child for browser compat reasons.) fixes #19604.
