- ResubmitPull is broken down into 3 flows similar to NewPull

- use a better icon for reopen
- fix subtle bug with close and comment
- more spacing fixes

- improve issue page icons and icon states
- make issue comments more like pull comments
- padding and spacing consistency across the board

drive-by fix: style the separator between pull submissions

path.Match does not work as expected; but our ACLs currently do not make
use of these anyway. glob/wildcard matching can be implemented in the
future.
