* Define colours within COL_TABLE * Do not output colours for non-terminal instances * Removed ":::" * Fixed indenting & spacing * Made output consistent throughout project * Reworded text to fit on standard 80 char wide Terminal screen * Made 'sudo raspi-config' warning (insufficient disk space) only show on RPi * Make "Installation/Update Complete" the final msg * Remove redundant messages * Simplify update available message * Confirm user would like to begin uninstall * If "git pull" string says "Already up-to-date.", place [i] before it * Colour Temp/Interface output * Made `pihole disable 5z` invalid * Added error fallback if invalid argument (not s/m) is detected * Quoted "$2" for consistency * Updated help text * L185/286: Replaced echo with redirect * User agents for adblock.mahakala.is/adaway.org unnecessary * Print newline on confirmation of repository reset * Add output to admin-related dnsmasq restarts * Return error message for "pihole -q" * Imply default checkout behaviour with y/N * Fix uninstall failing to remove pihole user * Print checkout 'git remote show origin' STDERR on new line * Replaced checkout "AdminLTE" wording with "Web Admin"
