main: do not trigger FocusGained on startup

Browse Source 
commit f045452743 introduced the
FocusGained autocommand. Unfortunately, for some systems this might
trigger already at startup, resulting in an unwanted redraw that might
clear the intro screen.

Therefore, add a timer, that enables the FocusGained autocommand after 5
seconds. The 5 seconds is somewhat arbritrarely, but we could change it
later if it turns out to be not useable.

fixes #1817
