#134 mdb-export does not escape column names

[James Cranch]

I was trying to export a table whose column names -- rather annoyingly -- contain commas. The output CSV does not have inverted commas around those column names, and thus CSV readers interpret it as multiple column names.

I am using mdbtools as it is in Debian stable (wheezy) right now; Debian identifies it as version 0.7-1.
