Releases for xhtml

This fix makes xhtml more compatible with the current development version of drupal8.

• Fix the html template replacement (called xhtml.tpl.php) to match drupal8's html.tpl.php. Fixes some PHP warnings/errors when loading a page.

Initial release.

Features

• Replaces the html template, which most themes should not need to override. Thus, this should work out of the box with many themes. (Please report bugs with pointers to particular themes which don't work!)
• Provides hooks to arbitrarily delivering content as XHTML
• Built-in support for disabling XHTML on certain pages and based on a client's Accept: header (only tested on apche, please report bugs concerning other httpds!)
