0.7.0

• Updated to Grind 0.7
• Updated design to better reflect the official Grind site
• Switched from Nunjucks to Stone, Grind’s new official first party templating engine
• Replaced usage of the babel-node cli wrapper by integrating babel-register directly into the booters (this should speed things up slightly and remove unnecessary headaches when forking).
• Fixed a bug in ErrorHandler when comparing error codes
• Updated Cli booter to use the new Runner class
