\class Utils::ProjectIntroPage
\brief Standard wizard page for a project, letting the user choose name
and path.
Looks similar to FileWizardPage, but provides additional
functionality:
\list
\o Description label at the top for displaying introductory text
\o It does on the fly validation (connected to changed()) and displays
warnings/errors in a status label at the bottom (the page is complete
when fully validated, validatePage() is thus not implemented).
\endlist
Note: Careful when changing projectintropage.ui. It must have main
geometry cleared and QLayout::SetMinimumSize constraint on the main
layout, otherwise, QWizard will squeeze it due to its strange expanding
hacks.
