using git checkout. The button shares the form with Stage Selected,
distinguished by the submit button's name/value pair.

Rename 'Changes' to 'Staging' in the page title and heading.
File names in both modified and staged file lists are now
clickable links that show the diff for that file. The diff
view shows both unstaged (index vs working tree) and staged
(HEAD vs index) differences.

Replace single-page layout with a frameset: left navigation frame
with repo dropdown and page links, right content frame showing
the selected page. Split the repo page into separate sub-pages:
branches, changes, remote, and manage.
Uses <frameset> for maximum compatibility with ancient browsers
(Netscape 2+, IE 3+). Clone and delete forms target _top to
reload the full frameset when the repo list changes.
