Added width and scale field for SavePicture

Updated width and height chunk pointers

- current_scale_width set to 07 (same as magnify)
- finish_scale_width set to 21 (same as magnify)
- current_scale_height set to 0A
- finish_scale_height set to 24

Remove bad files

Added separate width and height values for pictures

Added:
- Support for .scale2 function from ManiacPatch 211010
- When using picture effects, height is set to width
- Set both width and height if using .scale function

Bugfix:
- Assertion failed when returning width/height of non-existent bitmap (now returns 0)
- Maniac Patch rotation now works
