Kexi table view: update vertical header sections and fix cursor movement issues

Details:
* On row inserting and deleting, update the vertical header's model (instead of manually adding header sections)
  Major defect #3 at https://community.kde.org/Kexi/Porting_to_Qt%26KDE_4#Table_View
  "Update vertical header sections when # of records change"
* "select last row" works on when there are zero records
* on new row edit accepting do not jump to first row (fix regression)
* usability++: when editing is started, scroll a bit up to show next row if present
* usability++: when editing is started, ensure the very bottom of empty scroll area is displayed to help the user see what's there
* set internal margin of half of the horizontal scroll bar's height only when not in spreadsheet mode
* simplify "move to Nth row" and "move to last row" code
* internal logic change for vertical header: when new row editing starts, the new row data is added to the list of records, on Cancel it's removed so no need to check the newRowEditing flag
