Update freecodecamp_algorithms.py
Update freecodecamp_algorithms.py

User's portfolio page on freecodecamp.org has changed.
Last two table columns no longer contain hyperlinks to user's answers.
They contain solution's source code instead
(which is presented in a modal dialog box).

Main changes:
-- due to above, dataframe now consists of three columns
-- add an option to choose a directory where data will be saved
-- use __file__ instead of argv[0] from sys (import is no longer required)
-- revise docstrings
