Big overhaul and bug fixes

Browse Source 
- Fixes a bug that prevented getting input from the user in some terminals (https://stackoverflow.com/questions/6883363/read-user-input-inside-a-loop)
- No longer redirects stderr to /dev/null (Shows warnings and errors)
- Fixes checks about docker and debian
- Doesn't export color variables anymore (Idk why I did that in the first place?)
- Messages about successful operations only show if the operation was actually completed successfully
- Docker version, docker-compose version and user id now get printed in color
- Indentation fixes
...and more minor adjustments.
