14d6de059d implement newOrNil, changes to stdlib 
- newOrNil works like new, but sets the variable to nil
  if the heap allocation failed
- change stdlib to use newOrNil in openfile and openvolumeid
- changes to programs that use openvolumeid

ecff04a7a0 vga framebuffer: use 640x480@60Hz video timings 
- we still can only display 400 lines, so 80 blank lines
  are added at the bottom
- we get square pixels this way and are hopefully more
  compatible with monitors and other devices like
  scan converters and capture cards

3526060a19 sasm: bugfix for LBRANCH/LCBRANCH size changes 
- The LBRANCH and LCBRANCH directives
  create different instruction sequences
  depending on the jump distance.
  So the code size can shrink during the first pass
  when the jump distance can be determined (when the
  label that is the jump destination is parsed).
  In the long form, LOADREL/JUMP is used, which might
  or might not need 2 bytes of padding. With this bugfix,
  the padding is always added, either before or after
  the LOADREL indirect operand, so that the code
  size does not change depending on the padding
  required. Otherwise the code might shrink further
  on the second pass because a LBRANCH/LCBRANCH
  instruction no longer needs padding due to an
  earlier code size change.
