[Paraview] problems getting ParaView to use my reader plugin

[Utkarsh Ayachit]

Since 3.4, the qrc file is not needed unless you are adding qt
resources such as icons etc. to use in your custom code. The
ServerManager xml is almost always need when adding a new
filter/reader etc. The client-xml is only needed when adding readers,
writers or configuring where a new filter shows  up in the filters
menu.

You might also want to refer to the plugin wiki page (
http://www.paraview.org/Wiki/Plugin_HowTo ).
