Add new columns to the response

[Victorcorcos]

This PR...

• [x] Add the following columns to the result:
  1. P/Ativo
  2. P/Cap.Giro
  3. P/Ativ Circ.Liq
  4. Mrb. Ebit
  5. Liq.2meses
  6. Patrim.Liq

These columns are new ones from the fundamentus website table

• [x] Convert the values of all the columns to decimal values. (Very good if you want to play with these values later)
• [x] Updates the format of the print() output

Had to fix the Flask server though. The use of Decimal made it impossible to "jsonify" the result. So I opted so output it as float. Check it out.
