Fix positioning of New Passages

Currently when a new passage ("Untitled Passage X" ) is created it will appear as near to the top of the Story Panel as possible, which may be off screen if they used has paged down.

This is due to a bug introduced into the newWidget method back in 09-sep-2013.

The call to self.toLogical(pos) was changed to stored its return within the "qspos" variable, which is never used.

Fixed in branch "i012_position_new_passage"
