id: add bookmarks to id

Since bookmarks are no longer merged with repo.tags() as of
d012d95499f7, they don't show up in `hg id` as they used to. This adds
them back into the summary that `hg id` prints, and adds a
-B/--bookmarks flag alongside the -t/--tags and -b/--branch options.

Note this introduces a slight backwards-incompatibility: the summary
printed by `hg id` now separates bookmarks from tags with a space, as
seen below, instead of running it into the tags list.

Default summary output:

  $ hg id
  db815d6d32e6 tip/tag1 bm1/bm2

Output with --bookmarks:

  $ hg id --bookmarks
  bm1 bm2

See also afc84a879ac8 which adds bookmarks back into `hg summary`.
