Subject: [PATCH] Add --debug option to be improved on over time

Why:

 * first time using hugo I got very little info from --verbose output
   but I noticed there is quite a lot of useful DEBUG logging
 * asked for in other issues like https://github.com/gohugoio/hugo/issues/3514

This change addreses the need by:

 * adding a simple --debug flag which simply turns on debug level in stdout
   and logoutput if enabled.
