Created frontend for SeriesTreeModel::deleteFromSeries

Implemented frontend for SeriesTreeModel::deleteFromSeries. I hope
QPersistentModelIndexes work as advertised. From the qt-sources it seems
that a QPersistentModelIndex is automatically updated by
QAbstractItemModel when calling begin(Remove|Insert)Rows. Testing worked
out fine.

While at it I found a bug in SmTreeModel. removeRows has to be called
with (i - 1) instead of (i) to remove the correct nodes.
