Render comment markdown

[nathonius]

This is easy to achieve, but problematic.

const textContainer = commentContainer.createDiv('trello-comment--text-container');
const text = textContainer.createEl('div', {
  cls: 'trello-comment--text'
});
MarkdownRenderer.renderMarkdown(comment.data.text, text, '', this);

This works great, but styling is all over the place. A few things that need to be handled:

• Element margins
• Text size
• Probably a "see more" / "see less" type function to show/hide entire comment text if its super large
