From Matevz:

1. Changes applying to TGedFrame:

Handle list of additional tabs by using inner class TabSubFrame to
store information about each extra tabs. Use member TList
*fExtraTabs to aggregate the information. This is used by
fGedEditor when populating the full class editor.

Redirect the update call to fGedEditor.

Remove TGWidget inheritance.

Remove interaction with TClass::fClassEditors. Now class editors
are managed my TGedEditor map.

2. Changes applying to TGedFrame descendants:

In constructor remove widget ID argument and set all arguments a
default value. In the constructor implementation erase code which
operates on now obsoleted TClass::fClassEditors list.

Add memeber fGedEditor. Remove members fPad and fModel as they are
available from fGedEditor.

In SetModel() remove checking of inheritance and SetActive() call.

3. TGedNameFrame: added tooltip displaying name, title and
class-name of the model.
