Title: Modified setBorder() in CellWriter.php

Modified `setBorder()` so that 'top', 'left', etc. are moved up one position in the array that is passed to `setStyle()`.

`setStyle()` just directly passes the $styles to `PHPExcel_Style_Borders::applyFromArray()` which looks for `$styles['left']`, not `$styles['borders']['left']`.
