Refactoring

Things that annoy me:
1) When my team decides to change everything from a std::vector to a std::list and don't just use typedefs to make the change seamless (I'm guilty of this too).
2) When a teammate insists on writing C code in .cpps (no SC++L, no classes), and then claims all the memory leaks are okay "because they're just little ones" [flaming].
3) My game in general.
