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
Initial support for SpreadsheetML drawings,implemented XSSFPicture, added ability to add pictures to workbook, refactored XSSFPictureData to be a subclass of POIXMLDocumentPart. Also refactored misc odds and ends in order to produce xml better compatible with what MS Office produces
