Let's not add new type converters. Can we add StructTraits for this instead?

Also, StructTraits and type converters should be covered by IPC OWNERS rules as
well.

I am checking at the possibility of using mojom types all through in blink, as
bajones suggested, if that's acceptable to all.
Or for now should I try to use StructTraits instead and keep using Web types in
blink?

@dcheng:
By StructTraits, are you referring to the file like:
https://code.google.com/p/chromium/codesearch#chromium/src/url/mojo/url_gurl_...

I was checking in the current codebase and noticed StructTraits have been
defined for very few files - apart from origin.mojom and url.mojom, few files in
tests.
Is this the preferred method over type_converters? I still see most of the
implementations using type_converters. Can this be taken up in separate CL?
