metrics must end with CRLF

Looks like metrics ending with just a linefeed are ignored:

    $ DATE=$(date +%s)    
    $ echo $DATE
    1388498354
    $ echo -n "lf 1 $DATE\n"     | ssh mon nc -w1 localhost 2003    
    $ echo -n "crlf 1 $DATE\r\n" | ssh mon nc -w1 localhost 2003

Back on the cyanite host:

    cqlsh:metric> select * from metric;
    
     period | rollup | path | time       | data
    --------+--------+------+------------+------
     105120 |    600 | crlf | 1388497800 |  [1]
      60480 |     10 | crlf | 1388498350 |  [1]
    
    (2 rows)

Carbon (I tested 0.9.6) accepts both LF and CRLF.
