Restore default role names in QStandardItemModel::roleNames()

Browse Source 
Amends 32b586864e3a4398da38c045f4ac0823c3dc3c57, which added an override
of QStandardItemModel::roleNames().  It's good for it to have its own
QHash so that roles can be added, and because
QStandardItemModel::setItemRoleNames() remains un-deprecated; but before
that change, they were the roles that QAbstractItemModel had initialized
from QAbstractItemModelPrivate::defaultRoleNames().  In particular, we
need "display" to map to Qt::DisplayRole by default; several tests in
qtdeclarative depend on that.
