- subcorpora sort on integers only again
- added subcorpus-level 'no-sort' mode (speeds up unsorted searches)
- added macro DDC_SORTKEY_MAXLEN (= 256): maximum string sort-key prefix for subcorpus->server transmission
+ allows us to use a static buffer in distributed server, speeds things up a bit
- added error-checking code to CQueryNode::AddOccurrences(); avoids segfaults with pathological queries like ("@die *" #right)
