elements; and an example to use those HTMLy elements to display a
hello world doc. Highly incomplete WIP.

that uses it looks nicer; this moves the complexity to places that
register elements without using 'class' (e.g. the internals of
frameworks that create elements for defining elements)

parsed' callback; pass the element's module to the constructor when
constructing a custom element (these are rather experimental changes
and we may want to go a different way on this stuff)

In mojom, there's a notion of a request/response pair. This CL teaches the JS
bindings not to GC a message pipe after a request has been issued but before
the response has been received.

This has the following implications:

 - There's no createElement() function any more. If you want to create
   an element from script, you have to use its constructor.

 - There's no async element registration. The parser will block until
   all the imports are imported when you use a tag name of a custom
   element that hasn't been registered yet, in case one of the imports
   defines it.

 - If you try to construct a non-registered element in markup, it
   turns into an <error> element.

 - <div>, <span>, and <error> are new built-in elements.

Previously we were using string concatenation to build up the directory
listing. Now we fetch some JSON from the server and use data binding to inflate
a directory listing.

This exmaple doesn't work yet because we're missing support for
template@repeat, but hopefully we'll get that soon.

Also, added support for setRequestHeader to XMLHttpRequest.

This CL is just a search-and-replace.

constructors to all registered elements

Docs: Fix the script in the example to actually clone the template contents, not the template element itself.

I had to also register for the text/plain mime-type
which turned out to be harder than expected.
Mostly due to my confusion with mojo_shell
using last-argument-wins argument parsing.
