/tg/station build script

This build script is the recommended way to compile the game, including not only the DM code but also the JavaScript and any other dependencies.

VSCode: use Ctrl+Shift+B to build or F5 to build and run.
Windows: double-click Build.bat in the repository root to build.
Linux: run tools/build/build from the repository root.

The script will skip build steps whose inputs have not changed since the last run.

Dependencies

On Windows, Build.bat will automatically install a private copy of Node.
On Linux, install Node using your package manager or from https://nodejs.org/en/download/.

Why?

We used to include compiled versions of the tgui JavaScript code in the Git repository so that the project could be compiled using BYOND only. These pre-compiled files tended to have merge conflicts for no good reason. Using a build script lets us avoid this problem, while keeping builds convenient for people who are not modifying tgui.
