Added utility package cmdr::help::tcl, dumping the help as Tcl data structure. Like cmdr::help::json, with less overhead to read into other Tcl code.
Updated tests to match the new auto-exit command.
Remade "help::query-actor" as method "find" of officers and private. Simplified the internals of auto-help. Provides the path lookup to framework users as well. Updated the documentation.
