[Paraview] Pre-load python macros & toolbar icons?

[pat marion]

You can install individual files or whole directories.  Just run
"cmake --help-command install" for help, or search in paraview's
source code for "INSTALL(DIRECTORY" or "INSTALL(FILES" for examples.

To add macros programatically- at runtime determine the path to the
python macro file you want to add (get the path to the paraview.exe
and then you should know where the .py file is relative to that,
search the source code for "applicationDirPath" for an example) then
just call the static method:

pqPythonMacroSupervisor::addMacro(label, filename);

Probably you only want to do this on the first run, after that the
macro is stored in the paraview ini settings file.  You need to call
addMacro before the macro toolbar is populated because the method to
refresh the macro toolbar is protected
(pqPythonMacroSupervisor::resetActions()).  The toolbar is populated
after the call to addWidgetForMacros() in pqClientMainWindow.
