Some improvements to size scripts

Browse Source 
- Added -L/--depth argument to show dependencies for scripts/stack.py,
  this replaces calls.py
- Additional internal restructuring to avoid repeated code
- Removed incorrect diff percentage when there is no actual size
- Consistent percentage rendering in test.py
