Support Esperanto

[freexploit]

Amazing plugin, thanks. I use Esperanto frequently I would love to see it working with your plugin. I'm happy to help as well if this is not something you see useful in the project.

It is easy if we find a trigram frequency file somewhere. :-)

I have not tried to do a trigram frequency tool, which this should be simple, but then we should find a comprehensible corpus of esperanto texts. I believe the gutemberg project may have such.

I will try to find the trigram file first. The second approach is a bit more work.
