* haunt/post.scm (post-slug): Allow posts to set their own slug field
and use that if available. Otherwise default to previous title-derived
slug behavior.
* haunt/builder/blog.scm (ugly-default-collection-template):
* haunt/builder/blog.scm (post->atom-entry):
Reverse appending of prefix and slash in generation of paths
for blog entries.
Previously if a user did not provide a value for any of the theme
keyword arguments, there would be an error. Instead, provide defaults
from ugly-theme.
* haunt/builder/blog.scm: (ugly-default-layout, ugly-default-post-template,
ugly-default-collection-template): New variables.
(theme): New defaults to keyword arguments.
