Version V1.5.1 of `rst.el`

Hi!

I just committed V1.5.1 of `rst.el` to the SVN repository:

  https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/tools/editors/emacs/rst.el


This release contains mainly lots and lots of refactorings and only a
few user visible changes. This is the log message:

  Lots of refactorings and a few minor improvements.

  User visible improvements and changes:
  * Improve and debug `rst-forward-section` and `rst-backward-section`.
  * Auto-enumeration may be used with all styles for list insertion.
  * Improve and debug `rst-toc-insert`.
  * Adapt change in Emacs to use customization group `text` instead of `wp`.
  * Bind `n` and `p` in `rst-toc-mode`.
  * `z` in `toc-mode` returns to the previous window configuration.
  * Require Emacs version >= 24.1.

  Lots of refactorings including:
  * Silence byte compiler.
  * Use lexical binding.
  * Use `cl-lib`.
  * Add tests and raise test coverage.

I'm running lots of unit tests so I don't think anything is broken.
Nonetheless this may be the case. Don't hesitate to give me feedback
in this case.

I'm still refactoring `rst.el` but I'm nearly through with it. When
this is complete I'm going to implement new features and improve
existing ones.
