FieldTest_CSVCreator now works correctly

FieldTest_CSVCreator:
- added a try/except to the part of createCSV that passes the file name
to the FieldTest_File creator. If there was an error in creation, then
we print the error message to a text file (saved in same location as
where the CSV is going to be saved).
- Added some fun messages to printout while files are being parsed and
stored in the List parsedFiles. Message is changed based on how long it
has been since the script was started.
- script prints out how long it took to finish at the end

_File:
- If “Connectivity Test Failed” is in the text, then no tests were run,
and _contains_Errors is set to True

FieldTest_File:
- If there was no Test performed, we put the file’s error type in as a
placeholder

basic_utils:
- added new error type “Connectivity Test Failed”
