Support for additional Part Types

[TomVanWemmel]

I noticed that there is no support for negating keywords and wondered if there is a particular reason for this.

Is it possible to add support for the following types to PredicateQueryCreator?

• NOT_IN
• NOT_LIKE
• NEGATING_SIMPLE_PROPERTY

I'm willing to work on a PR if I can get some pointers what needs to change.

It looked like a simple modification, so I took the liberty to implement it right away.

@mp911de Is there anything I can do to progress this issue?

It's us who is the bottleneck as we're busy with releases and bugfixes for the time being. We have your PR on the radar and will come back to it for the 3.5 release.

I had a bit of spare time left today (right before taking some time off during the holidays) and merged your PR. Thanks a lot.
