BUGFIX: ensure --resolve and -v work in multifile mode

rootCMD was changeds to have a PreRunE not a PersistentPreRunE that
caused --resolve and -v to be properly handled. This meant multifile
could not rely on --resolve or -v for anything useful (they were never
"set" from multifile's perspective)

Closes: #95
