New Wave Release on Sandbox

[Douwe Osinga (google)]

The new version of wave we just pushed has some rather fundamental
changes under the hood. We've done our best to make the impact on
existing robots as small as possible, but you still might see some
changes around the indexes elements. For example some form elements
(INPUT, TEXTAREA) used to have the requirement that they had to be
their own paragraph; so if a robot would add such a form element, wave
would automatically add a paragraph. Robots that rely on absolute
indexes of these elements will now be off by one. There might be other
corner cases but in general the impact should be not too bad.

We'll also pushed a new version of the client APIs with some bug fixes
and better index calculations. Also the python version has a new
method on document: GadgetSubmitDelta. It takes an existing gadget as
a first parameter and a dictionary with the state changes desired.
We're working on a tutorial walking you through best practices for
robot and gadget communication, but we didn't want to keep this from
you now.
