[Paraview] Add support for PARAVIEW_EXTRA_EXTERNAL_PLUGINS?

[John Biddiscombe]

There used to be a PARAVIEW_EXTRA_EXTERNAL_MODULES - which allowed you 
to compile modules into paraview - in fact it still exists, but probably 
nobody uses it any more since plugins have improved so much.

I have some users who want to compile paraview, and a couple of selected 
plugins, and then do a single "make install"

I've added PARAVIEW_EXTRA_EXTERNAL_PLUGINS to the main paraview cmake, 
which allows you to enter

vtkCSCSCommon;vtkCSCSFluent;vtkCSCSNetCDF etc etc etc

and then it prompts for paths to the sources, and compiles them at the 
same time as paraview itself.

Does anyone else need this functionality? Shall I add it to cvs? It's 
very simple - but does make life easier for the less experienced users 
(to manage one build instead of two).

JB
