INSTALLED_DIRECTORY - The install directory name for this plugin.

For ST3
    As descriped in http://www.sublimetext.com/docs/3/packages.html this script locations is one of
    Zipped: 
        "<executable_path>/Packages/Markdown Preview.sublime-package/Markdown Preview.MarkdownPreview"
        "<data_path>/Installed Packages/Markdown Preview.sublime-package/Markdown Preview.MarkdownPreview"
    Not Zipped:
        "<data_path>/Packages/Markdown Preview/MarkdownPreview.py"

    All passable path for ST3 are abspath (tested on windows)

For ST2
    The __file__ will be '.\MarkdownPreview.pyc' that means when this script is loaded,
    Sublime Text entered the directoy of this script. So we make use of os.path.abspath()
