ADDED: Patch by Ulrich Arnold: Get PoDoFo build under Visual Studio 2008 (Windows build, OpenSSL optional)

- PdfEncrypt.cpp: Introduced a new define PODOFO_HAVE_OPENSSL. If this is not set,
  all of the encyption functionality is removed and openssl-lib is not needed.
  The CreatePdfEncrypt-members throws an exception in this case, the same as GetMD5String

- PdfExtension.h: Return type of getLevel changed to pdf_int64, as the member variable is also pdf_int64

- PdfFiltersPrivate.cpp: VS2008 spits on #pragma GCC, therefore removed with #ifndef _MSC_VER

- PdfIdentityEncoding.h/cpp: Argument of GetUnicodeValue und return of GetCIDValue changed from long to pdf_utf16be

- PdfImage.cpp: Included PdfFiltersPrivate.h, this eliminates the manual declaration of jpeg_memory_src.
  In LoadFromJpegData jpeg_memory_src is used instead of jpeg_mem_src, to be independend of new API-function
  introduced in Jpeg9-library

- PdfSigIncMemDocument.cpp: Removed collision between windows and jpeg-headers

- PdfSigIncSignatureField.cpp: Was implicitly dependend on Jpeg-library. Now
  if PODOF_HAVE_JPEG is not defined, NULL will be returned as image
