Support CSV file format of Yahoo Finance in activities import #2288

Rearranged date keys to prioritize trade date over date due to both provided in Yahoo CSV.
If no currency is found in CSV make API call to gather currency info for symbol.
If no fee provided, default to 0 (fee free).
If no type provided, default to 'BUY'.
Next: provide UI warnings for both above.
