#162 Setting extra style interferres with base class

[pfaelzer]

When an extra style is used, wxFormBuilder creates code like this (C++):
this->SetExtraStyle( wxWS_EX_VALIDATE_RECURSIVELY );
Unfortunately, the wxDialog class sets an internal extra style (at least on the MSW platform). The call above erases that style. The code should be changed to:
this->SetExtraStyle( this->GetExtraStyle() | wxWS_EX_VALIDATE_RECURSIVELY );

Note that wxWS_EX_VALIDATE_RECURSIVELY is just an example. The problem appears with any extra style.

Fixed in wxFB 3.5.2-RC2.
