Improve the way that the WiX installation is found.

Now that we have registry access, we search the registry for the key
corresponding to the latest known WiX version, then determine the WiX
installation path and version number from that. The latter is now
available as a set of properties.

This searching code is also now not broken for 32-bit Windows...
