QCompleter::setFilterMode() add property filterMode.

QCompleter::setFilterMode(Qt::MatchContains) will enable filtering
out entries that contain typed characters in any place, instead of the
default behavior when only those entries that start with typed characters
are displayed. Qt::MatchEndsWith is also possible.
QCompleter::setFilterMode(Qt::MatchStartsWith) will bring the default
behavior back.
Task-number: QTBUG-3414
