* contrib/hbqt/qtcore/hbqtcore.h
* contrib/hbqt/qtgui/hbqt_hbqabstractitemmodel.cpp
* contrib/hbqt/qtgui/hbqtgui.h
- Removed: the usage of HBQT_TYPE_xxxx constants.
It was a hack to identify a few type of objects Qt had
not provided the mechanism to retrieve.
NOTE: there should be improvement in build speed of hbQT.
* contrib/hbqt/qtgui/hbqt_hbqplaintextedit.cpp
- Added: deletion of child widget of HBQPlainTextEdit.
