       fix not updating _NET_ACTIVE_WINDOW
       
       currently clients that set the input field of WM_HINTS to true
       (c->neverfocus) will never be updated as _NET_ACTIVE_WINDOW even
       when they are focused. according to the ICCCM [0] the input
       field of WM_HINTS tells the WM to either use or not use
       XSetInputFocus(), it shouldn't have any relation to
       _NET_ACTIVE_WINDOW. EWMH spec [1] also does not mention any
       relationship between the two.
       
       this issue was noticed when launching games via steam/proton and
       noticing that _NET_ACTIVE_WINDOW was always wrong/stale (i.e not
       updated to the game window).
       
       for reference I've looked at bspwm [2] and it also seems to set
       _NET_ACTIVE_WINDOW regardless of whether the client has WM_HINTS
       input true or not.
