Revision 1748075

bug 58787: reintegrate changes from ss_border_property_template branch at r1748074. The BorderPropertyTemplate allows changes to border formatting to be staged in a template and applied to a sheet at a later time. This reduces the number of intermediate styles created, reduces interactions with cell objects (CellUtil.get/setCellProperties), and makes it easier to make the same formatting changes to multiple sheets. This utility can currently apply border line style and border color. This utility also adds the ability to add a border around a cell range rather than a single cell. Contributed by Mark Murphy.
