Updated updater and fixed bugs

Browse Source 
Added basic testing implementations
    - WIP: only outputs the log file at end of a run.
    - added option '--dev-test' to be used when running and testing the
      program.
    - practice of feature will be within a docker container but can
      equally been used on a native system.

Created 'check_restoration' function for optimisation of repetition
    - simply ensures that the restoration at any point was successful.
    - if the restoration fails, the program logs and exits accordingly;
      otherwise, if it succeeded then at this point the program exits
      with a different exit code since something else went wrong to
      trigger a system restoration.
    - takes 2 arguments, the exit code of the restoration system and
      the exit code of the section which triggered the restoration.
    - refactored sections can be identified containing the
      'check_restoration' function call.

Removed trailing whitespaces.
