d3e16a4 Make Google Analytics injection optional (#336)
This allows switching GA client statistics on the client by setting these params in the config.yaml file:
 analytics:
   inject: false/true
   gtag: (your tag)
By default, GA analytics will be disabled.

Both worker and coordinator display version numbers in the console during startup. 
The coordinator displays its version number in the top right corner of the index.html page.
cbabe69 Track connected user count of workers. (#328)
If a worker (game) is shared, then without tracking players it's impossible to tell when it becomes 
available for a new game which leads to emulator share and crashes.
