Add table placement to the scripting API

QetGraphicsTableFactory::create() only reads settings already set on an
AddTableDialog and never depended on the dialog being shown, so make it
public alongside setTableName()/setAdjustTableToFolio()/
setAddNewTableToNewDiagram() on AddTableDialog -- this lets the scripting
API build and configure a dialog headlessly instead of exec()'ing one.

qet.addTable() requires a non-empty query: ElementQueryWidget and
SummaryQueryWidget both default to zero selected columns, so an empty
query silently produced a table with no rows rather than a sensible
default. qet.tables()/deleteTable() list and remove by a position-sorted
index. qet.setTablePosition() repositions one, since newTable() always
places a new table at a fixed (50, 50) and a folio with more than one
needs to move all but the first itself.
