The playground hasn't been touched for a while and a few things were
broken before this commit:
- Exporting as a standalone web application was broken because it still
attempted to load the templates like it was done in owl 1
- Resizing the editor tabs still tried to use `this.trigger`
While fixing the export feature, the files needed by the app were
factored out of hardcoded strings and into real files, as this makes it
easier to maintain, since these files get syntax highlighting.
The samples received the same treatment: there is now a `samples` folder
containing all the samples, it also contains a jsconfig, giving
autocompletion on owl functions while editing the files, and allowing
the owl import to look how it would when using owl as a node_module.
In the browser, this import is translated to the relative path of the
owl module using an import map.
The bundle pipeline can use a bit of a improvement:
Most of the process is moved from npm scripts to rollup.
Add package keys to smooth out the use of bundlers of the end users.
(Rollup by example check amongst others the main, module and browser key
to import the right version of a lib when needed).
Refactor rollup logic to make it more modular.
Add bundled module formats.
Add comments to tsconfig to see more clearly what's possible.
Add reference tag to help @types discovery in test files.
