The changes:
- The main change is to replace all leading tabs by 4 spaces.
- Opening curly braces ('{') are moved to new line.
- No more spaces between casts and the variable (e.g. '(int)counter' instead of '(int) counter')
- Space formatting may now be ugly in some comments (when the '//' was before tabs)
- Inherits (':') are now always on their own line.
