Previously every time WiX heat.exe ran it generated new GUIDs for all
the file components that MSI was going to install. Windows installer
deletes components if there is no software/component left that is
referencing it.
This patch uses the -ag flag instead of the -gg flag for heat.exe so
it will generate deterministic GUIDs based on the filename and other
things instead of completely random new one on each run.
In addition we schedule the upgrade to run after the new version has
been installed. This way old files are first replaced with the new
ones, shortcuts remain and are not deleted, pinned shortcuts remain
usable. Afterwards MSI uninstalls the old version, specifically the
components that are not reference anymore.
Test-Information:
Tested (a) two version upgrade with this patch and (b) an upgrade from
a version without this patch to a version with this patch.
a) The upgrade works as expected. MSI installs the new version and then
uninstalls the old version. The pinned shortcut stays alive and works.
b) In this case during the deinstallation files of the new installation
are deleted, since there are two components with different GUIDs which
however use the same filenames.
Running a repair on this installation, or first deinstalling the old
version and then the new one manually fixes this.

dist=1 on Windows now generates .msi instead, as long as wix_bindir
is set to the path of \bin\ for WiX.
nsis is no longer used
