Refactoring done (was: Strigi refactor)

The reason that it is hard to do away with the jstreams namespace is
that CLucene uses a few classes that are exactly the same as those in
Strigi. So for binary compatibility we cannot change these classes. We
can use some casting trickery to solve it, but that's not pretty.

Strigi:StreamBase<char>* a = getStream();
jstream::StreamBase<char>* b = static_cast<jstream::StreamBase<char>*>(a);
indexStream(b);

We would only need this in the CLucene backend. For other backends
this is not an issue.
