Improve responsiveness of Focus Event.
Hey,
I've just started using Vuhdo and am really enjoying it, but came up against an annoying little problem. I added an indicator for "PLAYER_FOCUS", but noticed that it always took around 500ms to actually draw the indicator when my focus changes. This was in contrast to eg the PLAYER_TARGET special event, so I checked in the code what could be the difference and with a bunch of trial-and-error I found that this change made the update instant.
