stringify: improve table format

This change updates markdown-table, the library used to serialize markdown tables. With that update comes options that make more sense: * `looseTable` is no longer supported (it’s a bad GFM feature) * `spacedTable` is now called `tableCellPadding` * `paddedTable` is now called `tablePipeAlign` Closes GH-476.
