Disabled two unused fields in Constants (DEFAULT_REPORTS_DISPLAY_PERIOD*).
Suppressed some warnings for Calendar.set in DatePicker.
Added todo for license and fixed small warning.
Created constant LOG_FILE_DATE_TIME_FORMAT for SimpleDateFormat.
Made fields private and converted some fields into local variables.
Split up the parseCurrentStatus method, closed the BufferedReader after reading the last line.
Small issues: final parameters/variables, whitespace, etc.
