Bug fix for unrecognized line issue, add support for reassemble packages

[johnzeng]

Bug fix for #5 , the root cause is the gmatch function, I don't use it to get the value in a bulk so in the second call of recurse, gmatch will return the value of last bulk.(in this case, is 'select')

Also support highlighting value size, reply number, and whole multi-bulk reply.

Also support reassemble tcp package which is mentioned in #1 . you can dump such package by using

redis-bench -d 1500 -n 1

Make sure your network interface have a MTU of 1500, otherwise, change 1500 to a lager number.
