templatekw: export ui.paths as {peerpaths}

It's sometimes useful to show hyperlinks in log output.

  "{get(peerpaths, "default")}/rev/{node}"

Since each path may have sub options, "{peerpaths}" is structured as a dict
of dicts, but the inner dict is rendered as if it were a string URL. The
implementation is ad-hoc, so there are some weird behaviors described in
the test. We might need to introduce a proper way of handling a hybrid
scalar object.

This patch adds _hybrid.__getitem__() so d['path']['url'] works.

The keyword is named as "peerpaths" since "paths" seemed too generic in
log context.
