Do some housekeeping and cleanup on the build scripts for Windows:
- remove Windows 32bit builds as support for this has been removed from
the mxe container;
- fix some warnings in the smtk2ssrf installer configuration;
- sanitise the output colour of the smtk2ssrf build script;
- add a docker based build script for the Windows installers;
- remove outdated and deprecated documentation and scripts.
