Some more TODOs (mostly refactoring + code cleanup)
Fix export of environment variables (dash vs underscore)

Previously they could contain dashes and then were only accessible
from within Perl, but not from within Bash.

From now on potential dashes in environment variable names are
converted to underscores ("_") before being exported. May affect some
hook or role scripts.
