Full refresh for the showcase website

[hughrawlinson]

gh-pages probably needs a full rewrite. I reckon we can design a nicer site than what we've currently got :) I have big plans for a nice unified visualizer and a benchmarker.

I'm working on this now. See the sndpeek branch (and its sub-branches) for a sneak preview.

Subtasks:

• Build sndpeek style visualizer
• Build benchmarker
• Build home page
• Establish maintenance "SLA"s so this doesn't happen again
• Style review
• Build commit-api powered changelog
• Investigate generated documentation using jsdoc
• Investigate automated dependency greenkeeper

Where 'investigate' means 'look into whether or not this helps us showcase meyda in the best possible light, decide whether or not we're going to implement in this iteration'

Close enough.
