Make the rgoue branch Go-only

The port is complete, so the C sources and their build system
(autoconf/automake inputs, Makefiles, Visual Studio project, doc
templates, RPM spec, C build/modernization notes) leave this branch;
they live on in master/modern-rogue for reference.

Also ports the last missing wizard command (things.c pr_list/pr_spec,
the '*' item-probability listing), rewrites README.md for the Go port,
and updates ARCHITECTURE.md's layout notes (game/ has no third-party
imports; tcell lives in term/).

Kept: LICENSE.TXT, rogue.png, rogue.desktop, ARCHITECTURE.md.
