Gerrit: Add 'Details' text to dialog.

- Add a splitter and a text browser containing detailed text
  for the change using HTML links for email and URL, allowing
  for removal of 'Open', 'Copy URL' buttons.
- Remove large tooltip from list, rename methods to toHtml()
  and use them for the details text.
- Parse out reviewer email.
- Display approval level with sign.
