Added Dockerfile and entrypoint script to configure API Urls

[darthcircuit]

I've created a basic Dockerfile that will allow people that are self-hosting the API to also spin up the IDE easily and configure the API URL setting by specifying an environment variable called API_URL

Build the image:
docker build -t judge0-ide .

Run Locally:
docker run -d -p 8080:80 --name judge0-ide -e API_URL="https://api.example.com" judge0-ide

This line causes runtime errors since the variable apiUrl is re-assigned within ide.js. To fix this, replace the const keyword with var.

Also, it seems like the defaultUrl variable is still used in some places. A possible fix would be to also replace this line in the code to a hard-coded value. Same goes for the extraApiUrl variable.

I'll update that tonight. Thanks!

I've updated my code to remove all references to defaultUrl and put the contents into apiUrl directly. I also changed my const to a var to match your request.

When i get more time, i'll add some changes to allow an environment variable to update the extraApiUrl
