upcoming werkflow changes

In a blatant attempt to make myself look good in the Developer Activity
report, I'm working (with bob's blessing) on the changes needed to
migrate werkflow to its new home at codehaus. The last couple of days
I've been bringing the build system into line and tidying the source
code so I can use checkstyle for the next steps, which are:

1. Replace the Werken Company copyright boilerplate with the Codehaus
one.
2. Migrate from the com.werken.werkflow package to the
org.codehaus.werkflow package.

So, this is a heads-up that there are more changes due in the next
couple of days that are likely to affect you if you are using werkflow
at the moment, and particularly if you have local modifications to the
werkflow source code.

Let us know if this is going to cause any problems.
