build-system: document how to create a Windows installer

These are the instructions that I use at this point.

Removed a long obsolete script - it's been many, many years since that last was
useful (it was still using qmake to try to build Subsurface)

+# Creating a Windows installer
+
+The scripts here help with cross building Subsurface and smtk2ssrf for Windows.
+
+The preferred method to create a Windows installer is to use our own docker
+image that has all the build components pre-assembled.
+All it takes is this:
+
+```
+cd /some/path/windows
+git clone git://github.com/subsurface/subsurface
+cd subsurface
+git submodule init
+git submodule update
+docker run -v /some/path/windows:/__w subsurface/mxe-build-container:1.1 /bin/bash /__w/subsurface/packaging/windows/create-win-installer.sh
+```
+
+This will result in subsurface-VERSION.exe and smtk2ssrf-VERSION.exe to be created.
