A bunch of fixes, with some new minor features! The new features are:
- Add --generator option for eunit, which lets you run individual test cases
- implement mib_first_files support in rebar_compiler_mib
- Support ignoring entire modules in xref results
- Add a --fail_fast switch to common test which aborts the whole test run as soon as one of them fails -- this feature is experimental
And for the bug fixes:
- update relx to 3.28.0
- Update hex_core and add mirror_of repo config
- bump erlware_commons to 1.3.1
- re-expose download/3 for backwards compatibility in git deps-related plugins
- Fix pkg name during update by using pkg_name understood by hex
- Fix load order for custom project builders and parse transforms
