Before this pull request, the 404 and 404-search templates where handled
as full HTML pages without the page context (layout).

With this pull request both pages are rendered inside the selected
themes layout. Additionally the 404 template now contains the "search
form" and the homepage link.

All Themes are already updated with the above changes.

This reverts commit 9fa8fab864.

Feature to change Sitemap priorities direct with the "config.ini" for
SEO. Additionally this commit adds the "lastmod" tag for posts.

- Set the Sitemap priorities for subtypes (Base, Post, Static, Tag, ...)
within the config.ini
- Values beween 1.0 and 0.0 or "false" to disable a subtype.
- Default priority is 0.5 as fallback. (see functions.php) The default
for "base" (Homepage) is 1.0.
- Disabled subtypes aren't available in the sitemap.xml (index).
- The sitemap for posts now contains the "lastmod" set the the post's
date.
