copy broken by newlines in cell

hey there, what a beautiful plugin you have!
unfortunately, I can't use it for analysing a contact database as my address fields are exported from my contact database with newlines (out of my control) and although your parser handles these fields and places them in cells correctly, i can't copy out of the cells because the newlines aren't escaped correctly for either OSX numbers or Google Drive.

Here's some test data that u can use to reproduce my problem:

```
"qwe","rty","uio"
"asd","fg
h","jkl"
"zxc","vbn","m."
```

here are my settings

and here is my sys conf:

atom 1.7.3, tablr 1.3.0, MacBookPro11,3, OS X 10.11.4 (15E65)

Also as a side note, the ability to open a new spreadsheet from the command palette would be very helpful :)
