- use watchdog only in long-polling as SSE has auto-reconnection hand…

…ling by the browser and the watchdog breaks the native mechanism

• restart sse connection only when it is really closed
• stop watchog if its already running on start (prevent multiple running intervals)

I had a merge conflict after a branch changing, some changes obviously got lost dureing conflict solving. Please try again.

There are no more error messages when using LongPolling - but the watchdog is broken.

With no traffic: after 60 seconds comes a new r - as it should
But that's stopping then. After 5 minutes the server is terminating and the client is immediately reconnecting (as it is supposed to do in this case) - but not the 60 second interval that should be coming from the client.
This results in the problem that when the internet connection is removed, I do get on the console a (expected)

GET http://wiregate/cgi-bin/r?t=0&s=SESSION&a=12/9/2&a=7/4/51&a=17/4/51 net::ERR_INTERNET_DISCONNECTED

but the client never recovers from that. I.e. when the connection comes back the r is never started again.
