prefsCleaner 2.0

- massive speed improvement !! m-a-s-s-i-v-e !
- small fix to the time format used in backup filenames (replace space with zeros)
- better tolerance for special characters within preference names (which counters [the one downside that v1.2 brought along](https://github.com/ghacksuserjs/ghacks-user.js/pull/321#issuecomment-354394222)).
- other minor things, mostly to do with Delayed Expansion and the removal of it

known issue (but not really an issue):
- it skips instances of `user_pref` that have any quote or double-quote before `user_pref` (like `// "this" user_pref`)
