database refactoring

[Timtam]

We do have separate databases for each language right now. This results in the following:

• german players can only lookup german card names
• when building a deck, you can only add in german cards, even if we already got more cards in english which just aren't translated yet
• same goes for any other language besides english

I'd like to rework the database interface to have one database which attaches any other language file and merges all the tables into one large table which contains a language column or something, so we can grab for english/spanish/whatever card names from whatever ingame language we like.

i'd be happy with adding a lookup fallback to english whenever you try to look up a card in your non-english language, but the card could not be found. That would allow to always look up english cards even when not currently playing with english english set as your main language.
