This commit transition the application to Angular 13, and refactors the
build process to use the Angular CLI instead of hacking a webpack config.
It also removes a lot of things: junk code, or features that are no longer
needed, like the following:
* The Codepeer history view of the various runs is removed
* The refresh review / add review buttons with their associated dialog
are removed
