Note markup support in Markdown release.

Improvements

rabbit

* Removed GDK rendering engine. (Because cairo is always available since a few
  years ago. If we can use cairo, there is no problem without GDK rendering
  engine.)
* Improved GTK+ 3 support. (It's not completed yet.) [Patch by okkez]
* Removed unused --server option.
* Wiki markup: Improved error message when unsupported markup is used.
* Markdown markup: Supported error message when multiple images exist in a
  paragraph. [GitHub#71][Reported by Colin Dean]
* Markdown markup: Supported note markup. [Suggested by yoku0825]

  Syntax is {::note}...{:/note}.

  Example:

	Normal text {::note}note{:/note} Normal text

Theme

* image-timer: Reduced memory usage.
* image-slide-number: Reduced memory usage.
* clear-blue: Removed indent of the first line in block quote.
