Description

Write a short description of the changes included in this pull request, also include relevant motivation and context. Have in mind the following questions:

1. What is the reason for the change? A new prop was added: requireScroll.
2. What is the improvement/solution? Snap devs can now optionally include the requireScroll prop in their footers. The prop ensures that the footer buttons are disabled until the snap ui content has been viewed. This prop also means that a scroll arrow is also passed along to the template renderer based on the isScrolledToBottom prop.
