New rdate-plugin

http://github.com/seanh/PyBlosxom-rdate

This may be buggy! I just finished it this second, but it's a pretty
simple plugin and seems to be working on my blog.

I use (my own reimplementation of) the rdate utility from the plugin
registry. It backs up the mtimes of your entries as metadata lines
inside the entry files themselves, and restores the mtimes of your
entries from these metadata lines. It's a standalone utility not a
pyblosxom plugin, pyblosxom simply keeps on using file mtimes as the
dates of posts.

This behaviour of altering mtimes got to be a menace though, it trips
up all sorts of programs. If caching is enabled then pyblosxom uses
the mtimes to determine whether an entry needs to be parsed again.
Sync tools like rsync tend to use mtimes to determine whether a file
needs to be transferred. My text editor thinks that a file has been
modified externally if its mtime gets changed while I have it open in
the editor, and it then refuses to save the file for me. And so on.

So instead I wrote a pyblosxom plugin that reads these #published
lines and uses them as the post dates instead of the mtimes. Now you
don't need to run the rdate utility to reset all your mtimes, just add
#published lines in your entry files and they will be used.

I also did a complete rewrite of the original rdate script, I think
the code is a lot better now and I made resetting file mtimes optional
so that you can still use the script to add #published lines to those
entries that lack them without editing the mtimes of the other
entries.
