As far as I can tell, scalatra-auth has no code dependency on scalatra-commands despite the sbt/pom dependency. scalatra-commands has a number of reasonably heavy-weight dependencies (scalaz/commons-validator) that I don't use in my project.
I've confirmed scalatra compiles and runs just fine with the dependency removed.
Removed the dependency of scalatra-commands from scalatra-auth as it …
…seems unnecessary and it drags in a number of transitive dependencies.
