* Moved the location of key mappings to allow for a user's own
  vimoutlinerrc file can change <localleader>. This was necessary
  because keys mappings with <localleader> are not dynamically
  modified if <localleader> is modified after the mapping.
* Commented out the <localleader>,, command - it is very old, points
  to a nonexistent file and is very probably never used.
* Cleaned up some comments formatting.
