Format file after downloading and saving to variable

The file can be changed by students unknowingly in a way that breaks the file parsing. This issue is to fix this as much as possible after downloading the file, and not during execution.

A possible error traceback:

I'll leave this open, but since the file format is very simple, the parsing should work most of the times. Also, this issue means a lot more refactoring and rewriting than I had anticipated, so I'll mark it as low priority.
