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
more code cleanup and refactoring: (a) removed references to ooxml schemas from XSSF enums, they should not depend on ooxml-schemas.jar
(b) removed "for testing only" constructors, the goal is to have a single, maximum 2 constructors for objects inherited from POIXMLDocumentPart
(c) more javadocs
