fixed the sorting of SearchDialog by age and by size, by using proper delegates for displaying the numbers. Removed the SR_REALSIZE_COL column, that is no longer necessary.

/** Use this class for displaying dates and sizes in a readable format, while allowing to read the
* real size in the column.
*
* To use:
*
* - in the QABstractItemView constructor, do a
*
* myView->setItemDelegateForColumn(SR_SIZE_COL,new RSHumanReadableSizeDelegate()) ;
*
* - each field must be filled with a string that allows a proper sorting based on lexicographic
* order. For Sizes, use this:
*
* myView->setText(SR_SIZE_COL, QString("%1").arg(dir.count,(int)15,(int)10));
*
* Note: there's no .cpp file, because the code here is really simple.
