Emacs Markdown Mode Files

Breaking changes:

• GNU Emacs 25.1 or later is required. And xemacs support has been dropped
• Face variables, such as markdown-italic-face are now obsolete. Use face names directly in code and customizations. The face names themselves are unaffected, so this shouldn't affect most users.
• Delete obsoleted aliases
• Internal variables markdown-font-lock-keywords-basic and gfm-font-lock-keywords are now obsolete. markdown-font-lock-keywords is now used instead, but users should use font-lock-add-keywords instead of modifying this variable.
• markdown-mode now adds entries to the beginning of auto-mode-alist rather than the end. If you were relying on the previous behavior in order to override these entries, you should fix the problem by following best practice and ensuring that your user configuration is loaded after the autoloads for markdown-mode are evaluated. (GH-331, GH-335)
