cbc-incr only supports 32 bit ints

When trying to initial a counter with any value equal or over 32bit max int (4294967296) the following error is generated:

$ cbc incr count_max --initial 18446744073709551610 --delta 1                         

Couldn't parse options: Value too large

Bad value '' for initial

Couchbase Server supports counters up to 64bit max int and I can set that via the python SDK using libcouchbase.
