Tweaked the auto-help command. Default to full format only when asking for a specific command, otherwise default to a simple list.
Fixed bug in lappend for common blocks. Was not appending, but overwriting with last :(
Extended DSL for privates with command to record category/section information for help. Extended the help system with a by-category format, and made it default when not looking for a specific command. ATTENTION: The API between help core and formats did change, the root actor of the command tree is now supplied. New common block *category-order* to declare a bespoke ordering of categories.
Bumped cmdr version to 0.5
