This patch allows for metadata entries in .txtl files.

Example metadata:

title
#metakey metavalue
entry body text

The patch looks like this:

The code is based on the standard pyblosxom entry parser for .txt-files.

I wanted pyblosxom to send application/xhtml+xml to browsers that claim to support it so I whipped together a pyblosxom-plugin to do it.

I needed to modify two files from pyblosxom too. First the cgi, pyblosxom.cgi to make it recognize HTTP_ACCEPT:

     req.addHttp(d)

I also needed to modify the default renderer to not escape the body of entries:
