No longer one-file only

[BHare1985]

Many places in the source does it say it's a one-file only solution. I originally only downloaded Zebra_Database.php and quickly found out it has a dependency on external files for language and the formatter.

Depending on how important the one-file idea is to you I believe these are actually nice-to-haves (changing the language from non-english or having a nice formatter).

At the very least if you could update some of your documentation. I am happy to submit a PR if you'd prefer
