* fix zig fetch command in README
All URLs within build.zig.zon files must point to archives that never
change. However, the zig fetch command in the README.md adds a URL
that points to the `devel` git branch whose content changes whenever
the `devel` branch is updated.
I've updated the README a url that zig will resolve to a SHA before it
writes it to the zon file.

create resources folder during project_setup, and link with emscripten
--embed-file complained b/c the directory was empty, so I added
resources/placeholder.txt
I tested project_setup.sh (but not project_setup.ps1) -- the emscripten
build works
also, s/std.builtin.Mode/std.builtin.OptimizeMode
(std.builtin.Mode's source says: "///Deprecated; use OptimizeMode.")
