Documentation is not up to date :(

To simplify the dependences, the last version of the ZIM format only
recognizes one container/algorithm and this is xz/lzma2. This has been
decided at last dev. meeting. Please correct me Tommi if I'm wrong.

I think if we want to support another couple container/algorithm, this
newcomer has to bring really technical advantages. We should not switch
or add dependences only because one language/platform requires it...
Otherwise we will never find a sustainable solution.

So, my approach would be here to try to support the xz/lzma2 couple in java.

I see here two possibilities:
* Code the library directly in java
* Use libxz native code in java

What about these strategies?
