Change syntax from @inject @Named('foo') to @Inject(name: 'foo')

[llamadonica]

First of all, this is a totally stylistic change, and a breaking one at that. I just think the latter looks a little terser, especially because the form.

const foo = const Foo();

lends itself very well to optional named parameter. Named parameters are already used in a number of projects, e.g. polymer.

I have a pull request for your consideration.

This is a great idea, but it clashes a bit with our wish to use the https://github.com/google/inject.dart package to define the inject annotation (using this package would allow users to switch between DI containers without large code refacs).

I have created an issue for this on the inject.dart project list and hope you will vote for it google/inject.dart#2
