[patch] pubDate defaulting

This is a patch to dist/scripts/lib/Weblog.py from the 0.5 release of
Syncato to only set the pubDate element of a new document if there is
not already a pubDate element set.  Using XPath to check for element
existence may be a sledgehammer, but that's the only way I could quickly
see to do it.  

I had factored it out for use when editing the document as well but
decided to presume that documents aren't entering the database via means
other than Weblog.py (presuming further that You Know What You're Doing
if such is the case), and so will have a pubDate set if they're in the
database already.
