Pressship 0.1.6

What's changed

• Make pressship get -> cd checkout -> pressship version patch -> pressship publish work naturally for WordPress.org SVN checkouts.
• Treat SVN checkout roots as trunk/ for plugin discovery and version bumps.
• Route publish from a local SVN working copy to the release flow.
• Prevent local .pressship-svn working copies from being copied into SVN trunk or tags.
