Updated updater

Browse Source 
Added quiet operation
    - this will prevent STDOUT and STDERR from being displayed to the
      terminal, unless a decision is encountered - will not assume yes.
    - notifications are still sent since '--no-notify' can be used.

All echo statements responsible for outputting have been changed to
initial check if script is running in quiet mode.

'printf' statements which do not serve a specific purpose have been
changed to 'echo' commands.

'echo' statements that are responsible for displaying error messages are
now sent over STDERR instead of STDOUT.

Added '--full-clean' argument which will remove any possibly generated
files, by updater, from the system, including logs.
