Allow disabling table padding

Because on big tables it creates noise.

Setting "paddedTable" to "false" in package.json does 3 things:

1. Disable padding by `remark-stringify`
2. Use fixed width columns: `| --- | --- |`
3. Disable `remark-lint-table-cell-padding`

Linting is disabled because `remark-lint-table-cell-padding` has
no option (yet) for this particular style.

See: remarkjs/remark-lint#217

Prior discussion: #16
