pginstaller - pginst: More localisation work.

Log Message:
-----------
More localisation work. Now there is a wrapper MSI that gives the user a prompt for language before the installation starts.

Adds two fields to the translation schema for the language name in both english and the local language.

Moves the product code GUID into Makefile.config because it's referenced from the wrapper MSI.

Make sure we always put our version in the registry when installing, even if we don't install the server.

Along the way, fix a bug where the name of the icon binaries were accidentally translated.
