v1.0.0-alpha2

1.0.0-alpha2

The alpha1 release was a good opportunity to discuss the external component
API, and it was discovered that for various reasons, it was not optimal, and
could be improved.

Root components and environment

Root components now takes their environment from their constructor:

// Before:
owl.config.env = ...;
const app = new App();

// now
App.env = ...;
const app = new App();

Root components and props

We removed the assignation to props object from root components, since it
was not a "real" props object in the sense that it was not managed by Owl. But
it is apparent that it makes it harder to test components in the most obvious
way:

// this did not work in 1.0.0-alpha, but works now:
const myComponent = new MyComponent(null, testProps);
await myComponent.mount(fixture);
// rest of test

So, while it made sense to do that, the ease of testing components is also
very important, and it was decided to go back to the previous behaviour.
