Creator CSV export should double-quote multiline text fields

If you export data with multiline text fields that contain line breaks, the data from the multiline fields is not quoted with double-quotes. When you import the data into Excel or other CSV reading programs, the line breaks will cause the program to think it is the end of the CSV row and start reading a new row of data. Creator should double-quote fields that contain line breaks.

Example: Create an app with Field1, Field2, Field3 where Field2 is a multi-line text field. Enter:
Field1: Data1
Field2:
Data2a
Data2b
Data2c
Field3: Data3

The exported CSV will be:
Field1,Field2,Field3
Data1,Data2a
Data2b
Data2c,Data3

It should be:
Field1,Field2,Field3
Data1,"Data2a
Data2b
Data2c",Data3

Excel and other CSV-reading programs will import the latter version correctly.
