New buttons: Clear recent list button misaligned

Removing .button-small handles most of it. #doaction, #doaction2 also has a top margin of 1px that seems like it should be removed.

Patch seems fine. Either remove the 1px margin from #doaction, #doaction2 and #clear-recent-list or add it to all.

To be clear, 1px on those action buttons is to compensate for 1px on select:
