add windows WSL, git bash and bash as terminals

Would be really cool if you added a few if/else statements ##for windows wsl-bridge, git-bash, windows bash.

See #66 that would do it, but alas its 2 years old and not going anywhere.

xterm.js would very much solve this instead of using the old term.js which is 100% unmaintained.
