This commit also improves how forms are parsed by PHP by passing them as arrays, therefore making them easier to process.
Note: One of the files contains a debug statement that will be removed in the next commit
This commit also includes Chart.js for the whole project using Webpack. It also updates NPM packages to support ChartJS, and suppresses locale.js warnings from Webpack builds.
Gitignore removes the webpack bundle file since that file should be built each time dependencies/js code are modified.
This commit makes optional registration parameters optional; They should only be filled in after the user has submitted an application. The application will crash during registration without these parameters being optional, and adding them to the form would be illogical.
