Patch in large part by Philippe Saint-Pierre:

* Update Font preflet to use the layout-management. This already fixes a lot
  of issues.
* The were more issues with switching to default fonts and reverting fonts.
  Some fixed by Philippe and some fixed by myself.
* The preflet currently contains a work-arround for the problem that the window
  does not yet have it's final size until after BWindow::Show() has been
  completed. To be able to center itself anyways, it will open outside screen
  bounds and center itself then.

Note to Philippe: I had to fix some stuff in the Interface Kit to make this
more smoothly, so I was able to remove some calls to Invalidate() and such.
Also, the preview boxen and the menu fields align correctly now. Sorry if this
gave your gripes... :-)
