Add subclasses to QGst::Message so that it is possible to create and parse the various types of messages.

This commit also adds two helper template structures:
QGlib::Private::CanConvertTo and QGlib::Private::CanConvertFrom.
These are used to abstract away the conversion check from RefPointer::dynamicCast()
and the conversion sanity checks from ValueBase::set() and ValueBase::get().
This is required to make the Message subclasses work properly with these
functions, since they are not real Gst classes and do not have registered GTypes.
Each Message subclass gets a specialization for these structures which lets
RefPointer::dynamicCast() check the message type to determine whether to allow
the cast and ValueBase::set() to treat the subclass as if it was a Message.
ValueBase::get() will fail to compile if used with one of those subclasses
and this is done in purpose, since a Value can never contain one of these
(it will contain a Message, which has a GType!) and get() is not supposed to
allow upcasts, like dynamicCast() does.

So, to sum up, this trick allows you to do:

  QGst::MessagePtr msg = getSomeMessage();
  QGst::EosMessagePtr eosMsg = msg.dynamicCast<QGst::EosMessage>(); //checks if msg->type() == QGst::MessageEos

and

  QGlib::Value v;
  v.init<QGst::Message>();
  QGst::EosMessagePtr eosMsg = getSomeEosMessage();
  value.set(eosMsg); //will not fail, it will treat EosMessage as a Message

but not

  QGlib::Value v = getSomeValue();
  QGst::EosMessagePtr eosMsg = v.get<QGst::EosMessagePtr>(); //compilation error

Remove QGlib::String again. It sucks.

From now on the following policy will apply:
- Any methods that need to take a string argument will take a const char*.
This is because native gstreamer functions also take a const char* and in most
cases the programmer just passes an ascii string literal, so there is no need
to copy it in some string class and then let gstreamer copy it again. QString
is out of the question in this case, since it copies and converts to utf16, only
to let the wrapper function copy it again and convert it back to ascii. In case
the programmer needs to pass a QString to such a function, he should first convert
it to utf8 with QString::toUtf8(). This will be documented later.
- Any methods that need to return a string should return a QString.
This is because: 1) we need to make sure that the programmer won't do anything stupid
with the string, such as not free it or hold a reference to a free()-ed string, so
we can't return char* like the C functions do. 2) Usually these strings are used
for display or comparison, so the programmer needs to have an encoding-safe way
to do that and this is what QString offers. Returning a QByteArray and forcing the
programmer to convert it to unicode is not a good option.
