1.9.0

• Added a new List component.
• Text component:
  • The new textStyle and as props replace the old intent and size props.
  • When textStyle is not specified, it inherits the textStyle set by the closest parent (e.g. List) before reaching to the default "body1".
  • The weight prop was removed. Just wrap the text with <strong> (or <b>) instead.
• Flex component:
  • Children are wrapped in a <div> now. This helps to set the gutter between flex items (especially for those items that reset the margin to 0, like Text and List).
