Implement a Qt-like signal connection/disconnection system.

Features:
* New QGlib::disconnect method that behaves more or less like QObject::disconnect.
* Automatic disconnection when either the sender or the receiver is destroyed
  (this adds the limitation that the receiver must inherit QObject, for now)
* Future-proof. The exported methods are designed to be able to support
  different forms of connection in the future (such as connecting an arbitrary
  functor object instead of a member function). Support for different
  types of receivers (i.e. ones that do not inherit QObject) is also there.

Other changes:
* Moved all the connect/disconnect related stuff in connect.{h,cpp}
* Removed the ugly SignalHandler class. QGlib::connect now returns bool.
