Patch to split the nums array to avoid issue with Acrobat Pro

A bug exists in Acrobat Pro where if the nums array is deemed to be too large
when saving, Acrobat will split the array. If however, the array is broken on
an odd element the odd item is split where it's ID is kept in the first array
and its value is placed on the second leading to a "Bad Parameter" error when
checking compatibility. There is no maximum size of the nums array given in the
PDF specification, so why Acrobat is doing this is unknown (performance
benefits maybe). To ensure that anyone editing a FOP PDF in Acrobat Pro does
not come across this problem, this patch addresses it by splitting the nums
array if it exceeds a value (50).

Patch applied in rev. 1411352:
http://svn.apache.org/viewvc?rev=1411352&view=rev

I removed the re-definition of the getNums method in PDFPageLabels that had
become identical to the original one (in PDFNumberTreeNode). This avoids a
FindBugs warning.

Thanks for your patch!
Vincent
