more cleanup and refactoring of ooxml code,added more unit test and 3 rich examples: LoanCalculator, CalendarDemo and TimesheetDemo, numerous odds and ends improvements
1. moved ooxml enums into interfaces-jdk15, they are common and should be in the place as the interfaces 2. removed obsolete and deprecated classes 3. Fixed XSSFWorkbook.cloneSheet. Now it makes a 'true' deep copy of a sheet 4. ooxml has a compile-time dependency on scratchpad, fixed build.xml to reflect that
