Option to use a local wiktionary dump

Would be nice to use a local mysql db for querying.

Code from other projects could be reused like

Thumbs up for this idea! Downloading Wiktionary doesn't take that long, and if we could get all of this at once, that would be ideal.

Sounds like a good idea. Pull requests are welcome!
Is the purpose of this feature just to improve the speed of querying?
