[Paraview] 3.2 Plugin loading

[Sean Ziegeler]

What do you all think of adding a minor convenience to the plugin 
loading process?  I know it isn't that hard, but many of my users don't 
remember to use Plugin Manager or PV_PLUGIN_PATH, and don't want to 
bother adding it to their dot-files.  Thus I am forced to wrap all the 
executables with scripts that set it.

What about the following alternative:
Modify pqPluginManager::loadPlugins() to also load plugins from 
CMAKE_INSTALL_PREFIX/plugins  (where CMAKE_INSTALL_PREFIX gets set in 
CMake).

That way (assuming I do a make install) any plugins that I place in the 
plugins directory get loaded.

If you like it, what chance is there of getting it into the 3.2.1 
release?  I'm willing to try it myself and make a patch for you all at 
Kitware.

Thanks,
Sean
