Makefile, ox-hugo.el message formatting improvements

* ox-hugo.el:
  - Print the number of subtree being exported when doing C-c C-e H A.
  - Print the tag that caused a subtree/file to not be exported.
  - Misc message and code formatting improvements.
* .travis.yml: Disable the Entering directory/Leaving directory noise
  from make.
* Makefile: Add a blank line before each new instance of emacs in
  batch mode.
