[QGIS-Developer] Reducing the size of our download packages

[Régis Haubourg]

Maybe we could add a mechanism where proj grid files can be imported to 
the user profile, so any user could download grids.

Some caveats to avoid with multi profile management. I'd be in favor of 
storing proj grids once per user $APPDATA profile, not in each QGIS profile

Bien cordialement,
Régis Haubourg
