Disable the ul-style rule (#17)

> While enforcing a certain unordered list style can be somewhat helpful
for making the Markdown source easier to read with a screen reader, this
rule is ultimately too opinionated and noisy to be worth it, especially
because it conflicts with the editor's bulleted list toolbar button.
