Graphical gas price selection (#2898)
* Added gasPriceStatistics * WIP graph fas price stats (#2142) * Chart to select gas price in Extra Tx (#2142) * Gas Selection UI * Gas Price Selection: better UI (right octiles, point on graph) (#2142) * Gas Price Selection chart update using D3 (#2142) * Working UI, more fluid... (#2142) * Using the new gasPriceHistogram Call: display histogram (#2142) * Code Clean * Updated gas Selection explaination * PR grumble // Gas Price Selector (#2898) * Fixing linting issues

The lower the gas price is, the cheaper the transaction will
