Add mpages Emacs package

mpages is  a tool to quickly open a daily diary buffer with a timer and word count updated in the header.

;; Morning Pages are a concept named by Julia Cameron in her book
;; "The Artist's Way".  They are defined by the activity of waking up every
;; day and writing three pages of anything or everything that might be on
;; your mind.
