novnc: window in browser is no longer initially focused

[star-buck]

changing behaviour from 1701:

• when first time connecting to novnc, the window is not focussed.
• the initial window had a yellow frame when successfull connecting, now just stays grey
• initial window already is sized, where previously had a smaler size when asking for credentials and then scaled to whatever resolution was set when connected.

the last two issues are just observations, the first is anyyoing.

The last two are changes in the novnc code.
The size is changed as we now let novnc not search for the screen but tell it to use the screen :0 by default. So it knows its resolution and directly sets it.

window not being focused seems to be a novnc change. I can't get it to work without clicking first into the window.
edit: Installing the stonage version of novnc from stable makes this work.
