React 15.3.0 causes warnings for React Bootstrap

[mikewli]

Components are forwarding props to rendering elements, causing a lot of warnings, especially if the UI is comprised of many react-bootstrap components.

Facebook details the warnings here:

There are also warnings related to manually calling proptypes validation functions, eg:

Warning: You are manually calling a React.PropTypes validation function for the `dismissAfter` prop on `Alert`. This is deprecated and will not work in the next major version.
