... so that we can sanity check.

Remove all hacks/conventions of considering the last generated
file as project file, etc. and instead add attributes flags to
Core::GeneratedFile, giving fine-grained control of what to do
with the file. Implement static utility functions in wizards
that handle it. Add boolean XML-attributes "openeditor"/"openproject"
to the file elements used by the CustomWizard XML-specification.
Manually set the attributes in all wizards.

 * Remove PathChooser widget so that you need to use a proper dialog
   to select pathes. So typing into that PathChooser is no longer slow;-)

   entering a directory, so it was not a good choice.

This patch marks up invalid Qt versions as Desktop.

Make sure we add a the always existing invalid Qt version in the path
available in the targetselectionpage if no valid Qt versions could be found.

This way a project can be set up and loaded without a valid Qt version set up.
Trying to build this will fail of course. This is basically how we handled
this situation before we had targets, too.
