[missing] dart:html Node.normalize() method

This method merges dom text nodes together.

I have some code which uses Text.splitText(), and creates many single character text nodes - I assume that using normalize will help performance.

Please consider exposing this method in Dart.

Would be useful- I hacked together something for some unit tests I did elsewhere:

I did something similar. Not sure what the performance implications are. It didn't seem to matter in my use case.

Flagging as being a missing method from DOM
