TinyMCE 4.0.1~core1

	* [Bug] Fixed Bug #254 - TinyMCE File browser needs to be alphabetical
	* [Bug] Fixes in the navigator to ensure that files are prepended with the correct directory name.
	  This was causing issues from changing to the top directory "" or ".", and the system not recognizing
	  that path translated to public/tinymce.
	* Minor style tweaks to the navigator icon and list views.
	* Updated TinyMCE to 4.0.1 from upstream.
