Specify in README.md the list of languages into which the Pixel Dungeon is translated

Now we can only guess that the application is available only in English.

There is a version with translations on the play store, but that is a fork done by a completely different developer and has nothing to do with watabou at all.

I'm not against "officially endorsed translations" - it's totally up to the author if they wanna do that or not, though.
