parseCSV 0.3.2

This is primarily a bug-fix release for a critical
bug which was brought to my attention.

- Fixed a critical bug in conditions parsing which
  would generate corrupt matching patterns causing
  the condition(s) to not work at all in some
  situations.

- Fixed a small code error which would cause PHP to
  generate a invalid offset notice when zero length
  values were fed into the unparse() method to
  generate CSV data from an array.

+Notice: If you have been using the "parsecsv-stable"
+branch as an external in any of your projects,
+please use the "stable/parsecsv" branch from this
+point on as I will eventually remove the former due
+to it's stupid naming.

+- Small change to default output settings to

+  Only the LF (line feed) character was used
+  by default to separate rows, rather than
+  CRLF (carriage return & line feed).
