ComplexKey converts longs to strings

I previously added this as a comment on JCBC-41

Query q1 = new Query();
long time1 = 0;
long time2 = 99999999;
long time3 = 99999999999l;

q1.setRangeStart(ComplexKey.of(time1));
q1.setRangeEnd(ComplexKey.of(time2));
q1.toString() --> ?startkey=0&endkey=99999999

q1.setRangeStart(ComplexKey.of(time1));
q1.setRangeEnd(ComplexKey.of(time3));
q1.toString()) --> ?startkey=0&endkey=%2299999999999%22

It's throwing quotes around the long value.
