v5.0.0

• fix(parseComments): left trim comment description when used as name of section
• feat(tags): a custom tag with only a type of markdown and no name will now result in just a DOM string instead of creating an object.

/**
 * @customTag {markdown} Hello *world!*
 */

Before:

customTag: {
  description: '<p>Hello <em>world!</em></p>',
  type: 'markdown'
}

After:

customTag: '<p>Hello <em>world!</em></p>'
