style files duplicated

[exaos]

When I eval org-publish-blog, the content of style directory has always been copied to the PUBLISH_DIR. I thought it might be a bug.

yep there are several ways to copy directories:

• copy the directory (lazy version)
• copy each files one by one (slower but copy only needed files)
• synchronize faster but not standard

AFAIK there is no way to synchronize directories using emacs lisp. Anyway https://github.com/renard/dired-sync could be used.

Similar to #21 and #15
