Add column layout skeleton and git-column
A column option string consists of many token separated by either a space or a comma. A token belongs to one of three groups: - enabling: always, never and auto - layout mode: currently plain (which does not layout at all) - other future tuning flags git-column can be used to pipe output to from a command that wants column layout, but not to mess with its own output code. Simpler output code can be changed to use column layout code directly.
