Some code simplification in the new URL generation classes.

Also loosened things up a bit in the OfbizUrlBuilder class: allow object construction with partial information - required by some services. I don't like this approach because it makes it possible to create nonsensical URLs, but it is a necessary evil to keep the existing code working.
