* Optimizations.
* More VM protections.

! Fixed: a nasty construct in :clear() method where slots were
being disconnected and connected again increasing the unnecessary
object destruction/creation.
* contrib/hbqt/tests/demoqt.prg
* contrib/hbqt/tests/testbrow.prg
! Minor guards.
; NOTE: all the hbQT related test programmes are working flawlessly.
hbIDE still reports "reference to freed block" error but
this is not due to hbQT, instead, the complex object
relationship of hbXBP/hbQT/hbIDE classes. This is only
visible when hbIDE is linked without :destroy() mechanism.
BUT no GPF whatsoever. With :destroy() calls hbIDE EXITS
normally.
