Bug fixes:
* `alienv` works properly with the latest version of `environment-modules` (4.1.0): the problem was mainly affecting macOS users installing the package with Homebrew
* On some configurations, `aliBuild` did not determine whether to pick a system package or not. This is why the check script wasn't run with `bash` though we use bashisms in our recipe. We now force system checks to be always performed with `bash`
Improvements:
* Remote repository fetches are no longer performed by default, resulting in zero "fetch errors" and a much faster `aliBuild` startup time. This is useful when rebuilding frequently
* Fedora has been added to the list of supported platforms
* In non-debug mode, we now show the build percentage: it is guessed from stdout and useful for CMake-based projects
