Upgrades to ui: wider and show request parts (body and headers)

@shelbys 

A few eye candy feature changes:
1) Now displays Request Body + URL + Headers AND Response Code, + Headers + Body;
2) Made displayable area wider – often, it seems cramped; and max-width was at 960px; i.e. made it 1100px;
3) Add "Notes:" when displaying notes;
