Roll20 Role Selection per Jayspur11

This extension redirects the default request to the Roll20 Virtual Tabletop, adding params to ensure you join as a Player, rather than a GM, when entering a game you have GM permissions for. Then, you don't risk accidentally seeing the GM's notes when you join a game where you rotate between being a GM and a player!

If you want to switch to GM mode, you can do so once you've entered the game, and the extension will not stop you.

The code for this extension is available on GitHub. Issues and pull requests welcome!
