Moved the 3rd party package URLs to a separate file External-mingw32. This allows us to update to new versions without having to modify the script and makes it easier to figure out which packages and which versions are used.
Added a new script build-depkgs-msvc.cmd which does the same thing as build-depkgs-mingw32 except they are built using Microsoft Visual C and placed in the depkgs-msvc directory. There is also an External-msvc file to describe the packages.
Updated README.mingw32 with the updated instructions.
Added a couple of missing files to the installer for PostgreSQL.
