Unsupported ESTree node types with the walker

[ehmicky]

The walker at src/walk/index.js does not catch all the node types defined by the ESTree spec.
Example:

const node = acorn.parse('switch (1) { case 1: break; }');
assert(node.body[0].cases[0].type === 'SwitchCase');
let called = false;
walk.simple(node, {
  SwitchCase(){ called = true; }
});
assert(called);

I found this problem for the following ESTree types: SwitchCase, ClassBody, TemplateElement, ExportSpecifier.
The following abstract types are also missing: Declaration, ModuleDeclaration.

The code was written against an old version of the format. It's probably straightforward to add these -- want to submit a pull request?

Done in #558

What's the status of this? I apparently ran into this issue where my SwitchCase wasn't being called in walk.recursive; it seems this was a known but which has been fixed but following the link it appears that PR hasn't been merged due to hesistancy to merge it?
