fix some minor maven procedure issues

- Delete target mvn-deploy. afaik, it has never been used, and it 
doesn't work as written. It'll be easy enough to add back
if we decide some day that our maven artifacts should be at
sonatype instead of google code.

- Add description to target mvn-install.

- Rename -javadocs.jar to -javadoc.jar for consistency with 
previous versions published.

- Note that -precajole.jar is a temporary hack.

Please explain why the description in particular is suppressed. If it is because
this target doesn't work at all, perhaps it would be better to say so in the
description?

I don't want to clutter up "ant -p" output with targets that don't work

Please add a comment to that effect. I was not aware of "ant -p", and so this
consequence was not recognizable.

I decided to just delete the mvn-deploy target instead.

Then explain in the log message why you're deleting it.
