Thanks

Everything here has been cannibalized from elsewhere and dropped into mocha's reporter facility. Many thanks to:

• @maurelian - once posted a slack picture of mocha reporting gas output instead time. Idea from him.
• @cag - wrote a really nice gas stats utility for the Gnosis suites. The table borrows from / is based his work.
• Neufund - expressing gas usage as a ratio of the block limit in their ico suite. That comes from them.
