REVISION SUMMARY
  KURLRequester's acceptMode property has been introduced in KIO 5.33 (but Kexi's minimum supported KF5 version is 5.16.0).
  With older versions, the KUrlRequester's fileDialog() has to be modified directly.
  
  To be able to do this depending on the KIO version, set the property in the class constructor instead of the .ui file.

TEST PLAN
  Compiles fine now with KDE Frameworks 5.32 which failed before:
  
    In file included from /home/abuild/rpmbuild/BUILD/kexi-3.1.91/src/widget/KexiDBCaptionPage.h:24:0,
                     from /home/abuild/rpmbuild/BUILD/kexi-3.1.91/src/widget/KexiDBCaptionPage.cpp:20:
    /home/abuild/rpmbuild/BUILD/kexi-3.1.91/build/src/widget/ui_KexiDBCaptionPage.h: In member function 'void Ui_KexiDBCaptionPage::setupUi(QWidget*)':
    /home/abuild/rpmbuild/BUILD/kexi-3.1.91/build/src/widget/ui_KexiDBCaptionPage.h:88:25: error: 'class KUrlRequester' has no member named 'setAcceptMode'
             file_requester->setAcceptMode(QFileDialog::AcceptSave);
                             ^
  
  Still builds fine with newer versions, tested with 5.45.0 and 5.55.0.
  
  Also, the Destination file requester in the New project assistant still is in Save Mode, tested with KF 5.32.0 and 5.55.0.
