gatsby 1.0.0-alpha4

on Node.js Yarn

Added

• Add more file extensions to file/url loader config. Default to url-loader unless it never makes sense to use data-uri e.g. favicons.
• Use api-runner-browser for calling browser extension APIs/replacements. Prep for plugin system.
• Add extension API clientEntry that let's site code and plugins to run code at the very start of client app.

Changed

• Add config to uglify to ignore ie8.
• Disable building AppCache until can research if useful.
• Turn on screw_ie8 options in UglifyJS.

Fixed

• Actually use the "sources" key from gatsby-config.js for looking for markdown files. This will be getting an overhaul soon.
• Don't use null-loader for css during the build-js stage as this prevents offline-plugin from caching files referenced in your CSS.
• Add missing publicPath for build-html step.
