CVS Export doesn't escape commas and linebreaks

[AndyScherzinger]

For testing of the CVS export I added 3 readings and knowing that I'll do an CVS import afterwards I added line breaks and commas in the Notes fields of the readings which then leads to a broken CVS export since they aren't escaped to you end up with several lines with completely different content differing from the first line that defines all the included columns.
