v1.96.0

Full open-source release of Signus: The Artefact Wars

Note: signus-data source tarball will not build as is on GCC-11 or other C++17 compilers. You'll need to apply one of 3 workarounds:

• run configure or make with CXXFLAGS="--std=c++03"
• patch the source with commits e10a6a6 and 796f179 before running make
• or build with GCC-10

v1.96.0-rc1

Release candidate for Windows testing.
