The `prefsCleaner.sh` script chdir()'s to the script's directory on
execution, which isn't necessary at all, and also means that has to
reside within the Firefox profile directory, rather than being callable
directly from the Git clone.
`updater.sh` has the same "problem", but honours the `-p` switch to let
the working directory be overridden.
This patch removes the unnecessary code, such that the `prefsCleaner.sh`
script works on `./user.js`.

Changed permissions of prefsCleaner.sh from 644 to 755 to be able to run it via "./prefsCleaner.sh" with out first executing "chmod +x prefsCleaner.sh".
- add -s parameter to start immediately / skip prompt / run non-interactive
This is useful if the user wants to automate the process of updating the user.js and cleaning prefs.
- fQuit: error messages to stderr
- fFF_check: info msg to stderr
Better support for suppressing/redirecting stdout while still showing any error messages in the console, useful for example with `prefsCleaner.sh -s >/dev/null`
