Error when csv file contains escape quotes.

[huhudage]

if csv file contains escape quotes, such as key1, "a\"b\"c"

csv.lua will throw "unmatched quote" exception.

Yes, same to me. this should be ignored...i don't know why this is checked and an exception is thrown.

i think this code needs a rework.
