Improvements and suggestions

Since your midterm presentation you added great function to your project. It sends requests perfectly. I do see some cases where your blockly may fall through, and I wanted to fix one of those problems for you. Lets say we wanted to add more than one header, like User-Agent, Content-type, etc. How would a user add more than one header into the header? The same issue persists with other values like parameters. I added some code into my fork that parses multiple comma separated headers, and if you like that I would adopt to the parameter function. Just be aware whatever you do in the blockly needs to be written parsing wise in the server.js.

That's a great suggestion. Because the parser parses the JSON input, down the line we can add the ability to append headers when it finds the. ',' character. Will implement after adding other logic based features
