[Paraview] some ui issues

[Burlen Loring]

I attempted to use my plugin with the master branch today and ran into 
some UI issues.

I found it confusing that none of the properties were displayed until I 
hit the advanced button. Is there a way to make all the properties show 
up by default?

also, properties that were hidden via the show="0" hint were displayed. 
Is there a change in XML to hide props?
