    Attachment: LUCENE-3593.patch

guys thanks for the comments! I incorporated uwes shortcut and fixed the name to FieldValueFilter.
I extened the testcase to also use deletions. Uwe, whatever you want to do feel free to upload
a new patch. I already added a changes.txt entry for this too...

> In some situations it would be useful to have a Filter that simply returns all document
that either have at least one or no value in a certain field. We don't have something like
that out of the box and adding it seems straight forward.
