Clickable elements like buttons, etc. should have a pointer type cursor on mouse hover so that the user gets to know that the element is clickable.

Repro steps:

1. Open sample bot from https://microsoft.github.io/BotFramework-WebChat/01.a.getting-started-full-bundle/
2. Type help.
3. Buttons are displayed.
4. Use your mouse to hover over one of the buttons.
5. The cursor is of default type giving the user the impression that the element is not clickable.
