Handle keepalives better (Closes #965)

Browse source 
Bedrock cuts off the last 3 digits consistently every time, meaning that the keepalive returned from bedrock is never fully accurate. However, if we multiply the value by 1000, then divide by 1000 when sending back to java, the proper value is returned.
