Handling connectivity

This issue https://github.com/cfdp/opeka/issues/94 addresses the problem

To summarize:

Current behavior: Under the advanced settings in the Opeka module, the reconnection settings can be configured:

• Activation
• Max reconnection attempts
• Reconnection interval (ms)

Unfortunately quite a few issues arises from the current implementation, see issue queue.

What we are aiming for:

When a user looses internet connection for a certain time e.g. 6 sec. (server side setting) reconnection should be attempted.

• While reconnecting
  • the client should be presented with an alert box announcing the state
  • other clients in the same room should see the label (reconnecting...) after the client alias in the user list
• The reconnection attempt should continue as defined in "Max reconnection attempts" - but a timeout should also be defined server side to prevent clients from abusing / exploiting the reconnect feature.

If the reconnection succeeds

• the user should receive the "same state" as before - same room, same alias etc.

Special case for the counselors when reconnecting:

• The room should pause!
