fix(init): shallow clone and reduce verbosity

[curbengh]

• git:

  • --recursive has been deprecated in git 2.13, --recurse-submodules is available in git 2.3 (possibly available in older version).
  • --depth=1 for shallow clone the hexo-starter, resulting in faster and smaller clone.

• yarn and npm:

  • ignore optional dependencies

• Reduce verbosity for all commands.

It's a major (non-breaking) change, perhaps more eyeball from @hexojs/core .

LGTM. Maybe add a prerequisite on the git version required in the readme?

@tomap @curbengh Maybe even a git version check when hexo init in a separate PR.

recurse-submodules has been available since git 1.8.0, which is even older than the version (git 2.1.0) used in Debian Jessie.
