Investigate passing unique id and course code into game for user studies

[bradbury]

For user studies, players will have to complete a pre-game and post-game survey in LimeSurvey. A unique player id is required to match the survey data and the game play log data. Need to investigate passing a unique player id and course code via the game url when a user presses "Play Game" button at end of pre-game survey in LimeSurvey. Will also need to store the id and course code in the game so that a player can retrieve it (if necessary) to complete the post-game survey.

Currently we get the CourseCode and StudentID by having the student put them in. Should look into to this later here is a forum post that might be helpful https://answers.unity.com/questions/1285359/how-to-read-url-parameters-from-unity-webgl-build.html
