Added csv output files. changed default settings (output to xls off,
autorecord on, enabled main loop to end when cook time reached)

List file is used to keep track of already existing records. Plan (for now)
is to use this to allow web ui to easily lookup old csv files to plot/compare them.
Delete test.csv
Delete tablefile.txt
