help.lua has been rewritten to support "/help command". New variable "command" has been added to plugins for the syntax (w/out slash) to be displayed in main help message. "doc" will be displayed upon "/help command". Output of >12 plugins has been reformated to utilize markup. There is a fairly standard style throughout plugins. get_word() in utilities.lua now has defaults for nil arguments.
