Required to run on the server database before using this patch:
```
alter table flavors add ord integer not null default 999;
update flavors set ord=1 where name='cappuccino';
update flavors set ord=2 where name='espresso';
update flavors set ord=3 where name='espresso lungo';
update flavors set ord=4 where name='latte macchiato';
```

This patch slightly changes structure of a `flavors` table. It adds
another column called `ord`, which is used for ordering of coffee
flavors / beverages on the graphs (to maintain the same color scheme).

Scripts `app.py` and `coffee_db.py` are modified to work with this
change.
Patch pro přidání dalších nápojů, teď obsahuje i malé Mate.
