Webserver calls are blocking if webserver is not running

[cdondrup]

Im trying to print the messages the Robot says on the screen as well using the web server:

strands_webserver.client_utils.display_content(self.display_no, "<h1>"+sentence+"</h1>")

But when the webserver is not running, this call seems to be blocking. I thinks this should not be the case if possible because the whole system would grind to a hold if the webserver dies.

Timeouts need to be added to the wait_for_service calls. I'm in meetings all day tomorrow, so please go ahead and fix.

Anyone did anything regarding this?
