[Paraview] Errors when using find_package(ParaView REQUIRED)

[David E DeMarle]

For the Streaming and Manta plugins I took the approach of having the
VTK and PV level code in sibling directories. The PV level was
processed first and a variable set that changes the VTK level
cmakelists behavior slightly (for example whether to findpackage vtk
or not and whether to include ParaView centric VTK level classes). One
tricky part was getting the ParaView client server wrapper and
instantiators turned on for the VTK level directory. The plugin macros
only take care of that for the ParaView level directory so the VTK
level directory had to be done manually.

Note: The cmake code for those plugins has not yet been updated to
work in VTK6/PV4 but making the VTK level directory a standard module
should simplify things significantly (I hope).
