Use static class members for propTypes and friends.

Convert several React.createClass usages to classes.

Move binding to the constructor.

Use ES7 style class members for event handlers so that 'this' is
automatically bound and each definition site doesn't need to manually
invoke 'bind'.

This makes all existing ES2015 class usages in components use the
same mechanism for binding.
