Change all member variables to the form m_fooBar because it is the preferred form in Qt (it was half and half between this and mFooBar, and a minority didn't have anything).
Place all references and pointers on the side of the type since it is the majority.
- mFoo -> m_foo
- foo -> m_foo (if it is a member variable)
- Type &ref -> Type& ref
- Type *ptr -> Type* ptr
