Subject: [PATCH] Added alire.toml so alr can build/edit itself (#575)

* Added alire.toml so alr can build/edit itself

Also bumped the patch number, as code changes from now own should appear in a
future release, and 0.7-dev means pre-0.7 according to semantic versioning.

* Code review fixes

* New workflow to check that `alr build` succeeds
