crawler update

Ok, the crawler underwent a major rewrite today -- it's a lot cleaner
now. :)

While crawling the working copy, it now detects property changes as
well as textual changes. `make check` continues to work, and I've
been doing a lot of manual tests.

(Side note: when I run `svn commit`, I get an XML file produced by
Greg H's xml-output-editor. However, it's pretty hard for me to
eyeball the results. I always end up passing this XML file to the
deltaparse-test program for readable output. Perhaps we *should* put
indentation into Greg's editor. :) )

The manual tests show <prop-deltas> being correctly emitted by the
crawler.

(By the way, Karl:) the one bug remaining is that after a commit is
successful, we need a new log entry which will move the
local-prop-file to the pristine-prop-file. It's funny. I run `svn
status` after a commit, and all the textual `M' labels are gone, but
the property `M' labels are still there. Of course. :)
