CoinMarketCap Enhanced

Adds some enhancements to the cryptocurrency site CoinMarketCap.com

**PLEASE NOTE**: Now that CMC has stepped up their game and added most of the important features I originally wanted by making this extension, it has essentially completed its purpose and will no longer be maintained. Thanks everyone :) An extension with a few small enhancements to CoinMarketCap.com which add a night theme, inline charts, volume-to-marketcap ratio column, auto-refresh timer, TradingView link, removes ads, and expands the main table to fill the entire window.
