[AndrewDWhite]

The amazon plugin needs at least the next step function #10 .

[AndrewDWhite]

Implemented the minimum features for the amazon plugin. To use it do the following.

First start the launcher's main java function.
java -jar target/webGameLauncher-0.0.1-SNAPSHOT-jar-with-dependencies.jar

Start up the plugin.
py -3.7-32 plugin.py token 8488

Wait a few seconds after you see a packet from the plugin requesting a login. It will look something like this (or alternatively wait a few minutes and this should have happened).

From http://localhost:8080/games click on the 'open notification in new browser' button.

Click on the button that appears on the plugin's configuration page.

Once the new page has closed wait a few seconds and it should have provided the games to the plugin and refresh the http://localhost:8080/games page to have them populate.
