start of code to generate dart:html using dart:dom scripts

This change is the start of code to generate dart:html using dart:dom scripts. It essentially just adds the scaffolding for dart:html, and implements the generation of the "Events" interface and "EventsImpl" classes. There's more to do before the result is actually usable. For example, this doesn't contain EventsImplementation--I'm assuming we'll take jacobr's handwritten version.

I didn't check in the ../generated/html folder yet, but let me know if that makes sense.

(Note: I started with a copy of DartInterfaceGenerator instead of inheriting, but it ended up causing extra duplication when merging Stephen's recent getter/setter change. I think inheritance will be an easier way to build up the functionality, because we're essentially saying "dart:html is like dart:dom, but apply these extra transforms". Once most of the methods are overridden it would definitely make sense to break the link.)

Hey guys, let me know what the next steps are from here. Cheers!

Looks OK as a work in progress.

No need to check in the results yet.
We should consider checking in only the merged 'release' 1 or 2 library files
instead of all 500+ impl files.  Dartdomgenerator should make the merged
version.

AddEventAttributes would be a better name.

I find this kind of string easier to read if you always break the string at \n:

     '\n'
     '  $TYPE get on() =>\n'
     '    new $TYPE(this);\n'

PTAL

@sra - how do you guys build the combined dart:dom today? I could look at doing
that integration. That would make me feel better about checking in because I
could include the output.

This was also commented out in FrogSystem, so I presume I should remove it there
too?

Did this in the updated code.

Done. Also removed these form the DOMType interface/class

Thanks. Sounds like we want to check in and keep hacking. I'll submit.
