#490 Class view doesn't update correctly upon add or delete class

[Reijo Tomperi]

• After adding new class and saving manually ctrl + s
  for .h and .cpp files, the Classes-view contains
  global(?) extra constructor and destructor for the
  class that was just created. So there are two
  constructors and two destructors in the list. Other
  pair is under the main and other under the class name.

Additionally, the constructor and destructor under the
class will open the header file if double clicked, when
they should open the implementation file. If project is
closed and reopened, it starts working again.

• After removing class (by using the remove from
  project-feature), it is still visible in the
  Classes-view untill you close and reopen the project.
  It should be removed from there when files are removed.
