v1.2.0

Changes since 1.1.1

Added

• If the package root contains a file doc_mainpage.{rst,md}, it is used instead of the
  README to fill the main page. This is useful if the content of the README is not
  suitable for the documentation main page.
• Add config parameter mainpage.title to set a custom title.
• Add config parameter mainpage.auto_general_docs to disable automatic creation of a
  toctree for files in doc/.
• Mark external links with an icon (sphinx-rtd-theme setting style_external_links).
