[Windmill-dev] asserts and waits

[Mikeal Rogers]

We're starting to add more asserts and conditional waits to the  
windmill controller API.

This is starting to get ugly, as we seem to have gone the xUnit  
router of using separate functions for every case. In the hope of  
keeping our API and test writing UI clean I'd like to change this.

I suggest we have only one wait() and one assert() and implement the  
additional functionality as keyword arguments to those functions. So,

assertNode(id="asdf") becomes assert(node={"id":"asdf"}).

Any complaints/issues, i know Adam has some concerns about adding the  
dynamic UI for this but the longer we wait to clean this up the worse  
it's going to get.
