add html game runner

Note: For the self-install to work, you must issue a Github release with tag 1.0.0

Neuro HTML Game Runner

Usage

• Execute neuro_html_game_runner.bat next to folders containing games with .html entrypoints. Only the single script is required.
• You can select what game to play.

What it does

• First, it downloads static-web-server if it are not already present.
• It writes the environment variable NEURO_SDK_WS_URL, if it exists, to a file /$ENV/NEURO_SDK_WS_URL relative to the game directory.
• It uses static-web-server to serve the files for the selected game on localhost:8787.
• The game can then be played safely from localhost:8787 in the browser.

Why?

• HTML games are safe to run due to the browser sandbox. However, they require a local server to run in order serve game files.
• Bundling a local server with the game is dangerous, as it requires executing untrusted code, subverting the security model of the browser.
• This script can be used with any HTML game to run it locally safely.

Dependencies

• https://github.com/static-web-server

Idea: Instead of using the batch file installer and the powershell runner, would it not be a better idea to just have a single script file that does both the downloading of the dependencies and the running?

there doesn't seem to be an easy way to make double-click-to-execute work out of the box for .ps1 files.

I want to get this as close as possible to the python script - can we add these headers?

"Cache-Control", "no-cache, no-store, must-revalidate"
"Pragma", "no-cache"
"Expires", "0"

Since games will be cycled through often, caching should be disabled
