v0.13.0

• Semi-breaking - store format was slightly changed (to support peer dependencies, #46). pnpm will continue to be compatible with the old store format, but rebuilding node_modules is recommended to take advantage of new features.
• #41 - Support --save, --save-dev, --save-optional and --save-exact. (@davej)
• #46 - Support modules being able to require() their peer dependencies (aka, emulate npm3-style flatness)
• #57 - Support simpler Windows terminals.
• Improve logging appearance (show which packages are being fetched and which are queued).
