the trailing newline was included in the password string, causing
authentication to fail. Use strings.TrimSpace to strip it.

Move a number of funcs/files in the top-level `main` package into a new
`util` package, so test logic can directly invoke functions like
RunMark(), etc. The main.go has been trimmed down to minimal sizing,
with former supporting funcs moved into `util` package, so they
can be run by unit tests.
