Handle "screen fbdev/WIDTH/HEIGHT" to force use of FBDev DGA instead of XF86

Browse Source 
DGA mode. In other words, root user can now use FBDev DGA though it's always
recommended to run SheepShaver with a normal user. Increase "ramsize" bounds
in the GUI and fully migrate to new "screen" modes. Remove "windowmodes" and
"screenmodes" defaults.
