Git panel integrated into the treeview pane: uncommitted changes with
diff stats, staging, commits and history, toggled from a git-branch
button in the treeview toolbar or the status bar. History is pinned to
the bottom half of the panel; commit patches open with diff syntax
highlighting from the already bundled language_diff.
