Add expandEnv function and use it in PipeReader family of monitors
expandEnv takes a string and expands the environment variables it can find. variable substringing (e.g. ${VAR:1} to lop off the first character) is not supported, but $VAR and ${VAR} formats are, with the former being delimited by punctuation, but not underscores.
