Tightening up admin

[iammattthomas]

Per conversation with Happy Cog, cleaning up the admin:

• Condensing padding and margins that are too big
  
• Matching font sizes to mockups
  
• Fix alignment of action buttons
  
• padding in comment counter
  
• line heights in category list
  
• button padding
  
• tablenav paging margins
  
• permalink save button
  
  

More to come.

Ryan mentioned that I inadvertantly reverted 7344 with this patch; I've emailed Liz asking about the actions alignment. I'd set them back to left-aligned to match the mockups.

[iammattthomas]

Weird... that should be [7344].

[iammattthomas]

Liz: "I think that if they are right-aligned, then "Actions" should be right-aligned too. No question." By the looks of things this was the original intention, the declaration in the CSS just wasn't specific enough to supercede the left alignment of table header items.

Right-align actions header, too
