line breaks inside quoted fields are lost

[amc1804]

When the CSV input contains line breaks inside quoted fields, like so:

c1,c2
foo,"bar
baz"

the parser drops the interior line breaks, yielding

{ 'c1': 'foo', 'c2': 'barbaz' }

rather than the expected

{ 'c1': 'foo', 'c2': 'bar\r\nbaz' }

That's with Python 2.7.6, REST Framework 2.4.3, and Django 1.5.8 on
Linux.

I was able to fix this by changing splitlines() to splitlines(True) in
parsers.py.
