Qt: Updates for 5.15.

Fix the following deprecation issues for Qt 5.15:

Use Qt::WindowFlags() instead of 0 in Qt >= 5.6.

Pass Qt::SkipEmptyParts instead of QString::SkipEmptyParts to QString::split() in Qt >= 5.15.

Use QMultiMap instead of QMap where we were using QMap::uniqeKeys().

Use QCP::Interactions() instead of 0.

Use '\n' instead of QTextStream::endl.

Use QWheelEvent::angleDelta() instead of QWheelEvent::angle().
