bugfix: Windows pushing title bar off screen

I'm learning the hard way that resizing the window is a big deal. Only
do this when someone explicitly requests it, otherwise follow LÖVE's
defaults.

Therefore we're also going to stop trying to be smart when showing the
log browser. Leave window resizing to manual operations.

Now initialization looks a lot more similar for the run and source apps.
