board/common: replace default editor, nano -> mg

This reverts an earlier change where nano was made the default editor in
a misguided attemt by yours truly to accomodate beginner users.

With the recent improvements of the CLI and the fact that the NETCONF
support has matured greatly, the need for a user-friendly editor have
diminished drastically.  Editing system files is now limited to devs
and the core team prefers Mg over nano and vi.

+Subject: [PATCH 1/2] Redcuce *quick* size and make help text in status area
+ permanent
+Organization: Addiva Elektronik
+
+In an effort to improve on the usability for beginners, without getting
+in the way of experienced Mg users, the initial help text in the status
+area is now shown permanently.  I.e., whenever Mg clears the statis area
+we show the help text.
+
+Since we now show the help text in the status area we can drop it from
+the *quick* help buffer and reduce the height to save screen estate.
